Piping Engineering Quotes

She led him past the engine room, which looked like a very dangerous, mechanized jungle gym, with pipes and pistons and tubes jutting from a central bronze sphere. Cables resembling giant metal noodles snaked across the floor and ran up the walls. “How does that thing even work?” Percy asked. “No idea,” Annabeth said. “And I’m the only one besides Leo who can operate it.” “That’s reassuring.” “It should be fine. It’s only threatened to blow up once.” “You’re kidding, I hope.” She smiled. “Come on.

The street outside is empty, lit only by a half moon; yet factory engines beat in the background and the working day is about to begin. Maggie steps out of the tenement and suddenly the street begins to fill with women, some running, some pulling their jackets around them, some lighting pipes, some, like Maggie herself, taking a pinch of snuff. From other tenements come other women, and soon all merge into one, like a herd of cattle off to market, clopping over the stone pavements and the cobbles, lowing with last night’s news.

Life up here may be simple but it’s not easy, and it’s not for everyone. Water runs out; pipes freeze; engines won’t start; it’s dark for eighteen, nineteen hours a day, for months. Even longer in the far north. Up here it’s about having enough food to eat, and enough heat to stay alive through the winter. It’s about survival, and enjoying the company of the people that surround us. It’s not about whose house is the biggest, or who has the nicest clothes, or the most money. We support each other because we’re all in this together. “And people either like that way of life or they don’t; there’s no real in-between. People like Wren and Jonah, they find they can’t stay away from it for too long. And people like Susan, well . . . they never warm up to it. They fight the challenges instead of embracing them, or at least learning to adapt to them.” Agnes pauses, her mouth open as if weighing whether she should continue. “I don’t agree with the choices Wren made where you’re concerned, but I know it was never a matter of him not caring about you. And if you want to blame people for not trying, there’s plenty of it to go around.” Agnes turns to smile at me then. “Or you could focus on the here-and-now, and not on what you can’t change.

A technical summary on pressure piping Engineering and Regulatory documents used in Quality Control and Construction of Pressure Piping

That's all the motorcycle is, a system of concepts worked out in steel. There's no part in it, no shape in it, that is not out of someone's mind [...] I've noticed that people who have never worked with steel have trouble seeing this—that the motorcycle is primarily a mental phenomenon. They associate metal with given shapes—pipes, rods, girders, tools, parts—all of them fixed and inviolable., and think of it as primarily physical. But a person who does machining or foundry work or forger work or welding sees "steel" as having no shape at all. Steel can be any shape you want if you are skilled enough, and any shape but the one you want if you are not. Shapes, like this tappet, are what you arrive at, what you give to the steel. Steel has no more shape than this old pile of dirt on the engine here. These shapes are all of someone's mind. That's important to see. The steel? Hell, even the steel is out of someone's mind. There's no steel in nature. Anyone from the Bronze Age could have told you that. All nature has is a potential for steel. There's nothing else there.

The next time you drive into a Walmart parking lot, pause for a second to note that this Walmart—like the more than five thousand other Walmarts across the country—costs taxpayers about $1 million in direct subsidies to the employees who don’t earn enough money to pay for an apartment, buy food, or get even the most basic health care for their children. In total, Walmart benefits from more than $7 billion in subsidies each year from taxpayers like you. Those “low, low prices” are made possible by low, low wages—and by the taxes you pay to keep those workers alive on their low, low pay. As I said earlier, I don’t think that anyone who works full-time should live in poverty. I also don’t think that bazillion-dollar companies like Walmart ought to funnel profits to shareholders while paying such low wages that taxpayers must pick up the ticket for their employees’ food, shelter, and medical care. I listen to right-wing loudmouths sound off about what an outrage welfare is and I think, “Yeah, it stinks that Walmart has been sucking up so much government assistance for so long.” But somehow I suspect that these guys aren’t talking about Walmart the Welfare Queen. Walmart isn’t alone. Every year, employers like retailers and fast-food outlets pay wages that are so low that the rest of America ponies up a collective $153 billion to subsidize their workers. That’s $153 billion every year. Anyone want to guess what we could do with that mountain of money? We could make every public college tuition-free and pay for preschool for every child—and still have tens of billions left over. We could almost double the amount we spend on services for veterans, such as disability, long-term care, and ending homelessness. We could double all federal research and development—everything: medical, scientific, engineering, climate science, behavioral health, chemistry, brain mapping, drug addiction, even defense research. Or we could more than double federal spending on transportation and water infrastructure—roads, bridges, airports, mass transit, dams and levees, water treatment plants, safe new water pipes. Yeah, the point I’m making is blindingly obvious. America could do a lot with the money taxpayers spend to keep afloat people who are working full-time but whose employers don’t pay a living wage. Of course, giant corporations know they have a sweet deal—and they plan to keep it, thank you very much. They have deployed armies of lobbyists and lawyers to fight off any efforts to give workers a chance to organize or fight for a higher wage. Giant corporations have used their mouthpiece, the national Chamber of Commerce, to oppose any increase in the minimum wage, calling it a “distraction” and a “cynical effort” to increase union membership. Lobbyists grow rich making sure that people like Gina don’t get paid more. The

The ceiling in the engine room was all gray pipe, but suddenly it had a very romantic tinge to it. She thought that she might be a fan of pipes, actually, that they looked quite nice all tangled up in the ceiling together, that they had kind of an air of sweetness, actually.

At times the engine stopped, and grown-ups and children climbed out of the carriages with tins to collect water from the engine steam pipes. This was the only drinking water that we had access to, and though it was hot and very rusty, it was the best drink I felt I’d ever had.

I had entered the Green [of Glasgow] by the gate at the foot of Charlotte Street—had passed the old washing-house. I was thinking upon the engine at the time, and had gone as far as the herd's house, when the idea came into my mind that as steam was an elastic body it would rush into a vacuum, and if a communication were made between the cylinder and an exhausted vessel it would rush into it, and might be there condensed without cooling the cylinder. I then saw that I must get rid of the condensed steam and injection water if I used a jet, as in Newcomen's engine. Two ways of doing this occurred to me. First, the water might be run off by a descending pipe, if an outlet could be got at the depth of 35 or 36 feet, and any air might be extracted by a small pump. The second was to make the pump large enough to extract both water and air. ... I had not walked further than the Golf-house when the whole thing was arranged in my mind. {In Robert Hart's words, a recollection of the description of Watt's moment of inspiration, in May 1765, for improving Thomas Newcomen's steam engine.}

It looked like the same car, except that for ever afterwards it seemed able to do 250 miles on a gallon of petrol, ran so quietly that you practically had to put your mouth over the exhaust pipe to see if the engine was firing, and issued its voice-synthesized warnings in a series of exquisite and perfectly-phrased haikus, each one original and apt … Late frost burns the bloom Would a fool not let the belt Restrain the body?

In my own city of Los Angeles, everyone will gladly pay a hundred dollars a month for cable television, yet would roar in protest if forced to pay that much for life’s elixir piped directly into their homes. When Governor Schwarzenegger declared a state of drought emergency, I studied my water bill closely for the first time in my life. For two months of clean drinking water, snared from faraway sources, and delivered to my house by one of the world’s most expensive and elaborate engineering schemes, I was charged $20.67. I spend more on postage stamps. If only everyone could indulge such ignorant bliss…

How many miles have we done in her?” she asked. “More than a hundred and fifty thousand,” said Arthur. “Have you checked we’ve got enough fuel?” “She’s as ready for us as we are for her.” “Then let’s go.” Arthur opened the boot and placed the suitcases inside. Then, from the workbench, he picked up the hosepipe and, using parcel tape, attached one end to the exhaust pipe and the other to a crack in the side window, padding the rest of the gap with an old beach towel. Finally, he climbed into the van to join June and turned on the ignition. “Where do you fancy going then?” June asked as the engine chugged. “We never made it to Barcelona and I always wanted to climb the steps up La Sagrada Família. It looks so beautiful in photographs.” “Then let’s go there first.” She reached out her hand to entwine her fingers around his. His eyes welled as he offered his wife a grin as broad as any he had given her during their lifetime together. Then he wiped the tears away and closed his eyes. “It’s you and me to the end, girl,” Arthur whispered. “You and me,” she repeated, and he could smell her apple blossom shampoo as she leaned her head onto his shoulder. And together, they set off on their final adventure together.

In the nineteenth century, scientists described brains and minds as if they were steam engines. Why steam engines? Because that was the leading technology of the day, which powered trains, ships and factories, so when humans tried to explain life, they assumed it must work according to analogous principles. Mind and body are made of pipes, cylinders, valves and pistons that build and release pressure, thereby producing movements and actions. Such thinking had a deep influence even on Freudian psychology, which is why much of our psychological jargon is still replete with concepts borrowed from mechanical engineering.

He flies as fast as she will go, lower than the black power lines, lower than the silver irrigation pipes, rending the air just above deep green leaves that wave in his wake, soaking up the mist he leaves behind. He glances ahead and prepares for his escape; the steep climb nearly within the grasp of approaching trees, the smooth rising turn which, like an unanswered prayer, twists slowly down and away, falling back toward the earth, lined up on the next rows. It is a dance of sorts, to the roar of the engine and the scream of the wind; a soaring, sweeping dance around the jealous pull of earth. It is a lonely, wordless dance, but it suits him.

The Roman general wanted to spare Archimedes, because he was so valuable—sort of like the Einstein of the ancient world—but some stupid Roman soldier killed him.” “There you go again,” Hazel muttered. “Stupid and Roman don’t always go together, Leo.” Frank grunted agreement. “How do you know all this, anyway?” he demanded. “Is there a Spanish tour guide around here?” “No, man,” Leo said. “You can’t be a demigod who’s into building stuff and not know about Archimedes. The guy was seriously elite. He calculated the value of pi. He did all this math stuff we still use for engineering. He invented a hydraulic screw that could move water through pipes.” Hazel scowled. “A hydraulic screw. Excuse me for not knowing about that awesome achievement.” “He also built a death ray made of mirrors that could burn enemy ships,” Leo said. “Is that awesome enough for you?” “I saw something about that on TV,” Frank admitted. “They proved it didn’t work.” “Ah, that’s just because modern mortals don’t know how to use Celestial bronze,” Leo said. “That’s the key. Archimedes also invented a massive claw that could swing on a crane and pluck enemy ships out of the water.” “Okay, that’s cool,” Frank admitted. “I love grabber-arm games.” “Well, there you go,” Leo said. “Anyway, all his inventions weren’t enough. The Romans destroyed his city. Archimedes was killed.

He reached the Devil’s River Bridge at sundown and half way across he pulled the cruiser to a halt and turned on the rooflights and got out and shut the door and walked around in front of the vehicle and stood leaning on the aluminum pipe that served for the top guardrail. Watching the sun set into the blue reservoir beyond the railroad bridge to the west. A westbound semi coming around the long curve of the span downshifted when the lights came into view. The driver leaned from the window as he passed. Dont jump, Sheriff. She aint worth it. Then he was gone in a long suck of wind, the diesel engine winding up and the driver double clutching and shifting gears. Bell smiled. Truth of the matter is, he said, she is.

The explosion tore away water pipes used to supply coolant into the bottom of the core, preventing the reactor from being fed with water by the mangled pumps. Unfortunately, the operators did not realise this - or were in denial, given the horrifying consequences a reactor explosion would entail - and their lack of understanding lead them down the wrong course of action which served only to exacerbate the situation and throw lives away. Instead, Deputy-Chief Engineer Dyatlov became convinced the explosions had been caused by hydrogen in the Safety Control System’s emergency water tank, and that the reactor must still be intact. Even though he had no real basis for this explanation - and if he had looked out of a window he would have seen that he was wrong - he acted on this belief for hours after.

In the nineteenth century, scientists described brains and minds as if they were steam engines. Why steam engines? Because that was the leading technology of the day, which powered trains, ships and factories, so when humans tried to explain life, they assumed it must work according to analogous principles. Mind and body are made of pipes, cylinders, valves and pistons that build and release pressure, thereby producing movements and actions. Such thinking had a deep influence even on Freudian psychology, which is why much of our psychological jargon is still replete with concepts borrowed from mechanical engineering. Consider, for example, the following Freudian argument: ‘Armies harness the sex drive to fuel military aggression. The army recruits young men just when their sexual drive is at its peak. The army limits the soldiers’ opportunities of actually having sex and releasing all that pressure, which consequently accumulates inside them. The army then redirects this pent-up pressure and allows it to be released in the form of military aggression.’ This is exactly how a steam engine works.

There was nothing pretty or elegant about their robot. Compared to the gleaming machines other teams had constructed, Stinky was a study in simplicity. The PVC, the balloon, the tape measure—in each case they had chosen the most straightforward solution to a problem. It was an approach that grew naturally out of watching family members fix cars, manufacture mattresses, and lay irrigation piping. To a large swath of the population, driveway mechanics, box-frame builders, and gardeners did not represent the cutting edge of engineering know-how. They were low-skilled laborers who didn’t have access to real technology. Stinky represented this low-tech approach to engineering. But that was exactly what had impressed the judges. Lisa Spence, the NASA judge, believed that there was no reason to come up with a complex solution when an elementary one would suffice. She felt that Carl Hayden’s robot was “conceptually similar” to the machines she encountered at NASA. The guys were in shock. They marched back up to the stage and looked out at the audience with dazed smiles. Lorenzo felt a rush of emotion. The judges’ Special Prize wasn’t a consolation award. These people were giving them real recognition.

Last Thoughts On Woody Guthrie When yer head gets twisted and yer mind grows numb When you think you're too old, too young, too smart or too dumb When yer laggin' behind an' losin' yer pace In a slow-motion crawl of life's busy race No matter what yer doing if you start givin' up If the wine don't come to the top of yer cup If the wind's got you sideways with with one hand holdin' on And the other starts slipping and the feeling is gone And yer train engine fire needs a new spark to catch it And the wood's easy findin' but yer lazy to fetch it And yer sidewalk starts curlin' and the street gets too long And you start walkin' backwards though you know its wrong And lonesome comes up as down goes the day And tomorrow's mornin' seems so far away And you feel the reins from yer pony are slippin' And yer rope is a-slidin' 'cause yer hands are a-drippin' And yer sun-decked desert and evergreen valleys Turn to broken down slums and trash-can alleys And yer sky cries water and yer drain pipe's a-pourin' And the lightnin's a-flashing and the thunder's a-crashin' And the windows are rattlin' and breakin' and the roof tops a-shakin' And yer whole world's a-slammin' and bangin' And yer minutes of sun turn to hours of storm And to yourself you sometimes say "I never knew it was gonna be this way Why didn't they tell me the day I was born" And you start gettin' chills and yer jumping from sweat And you're lookin' for somethin' you ain't quite found yet And yer knee-deep in the dark water with yer hands in the air And the whole world's a-watchin' with a window peek stare And yer good gal leaves and she's long gone a-flying And yer heart feels sick like fish when they're fryin' And yer jackhammer falls from yer hand to yer feet And you need it badly but it lays on the street And yer bell's bangin' loudly but you can't hear its beat And you think yer ears might a been hurt Or yer eyes've turned filthy from the sight-blindin' dirt And you figured you failed in yesterdays rush When you were faked out an' fooled white facing a four flush And all the time you were holdin' three queens And it's makin you mad, it's makin' you mean Like in the middle of Life magazine Bouncin' around a pinball machine And there's something on yer mind you wanna be saying That somebody someplace oughta be hearin' But it's trapped on yer tongue and sealed in yer head And it bothers you badly when your layin' in bed And no matter how you try you just can't say it And yer scared to yer soul you just might forget it And yer eyes get swimmy from the tears in yer head And yer pillows of feathers turn to blankets of lead And the lion's mouth opens and yer staring at his teeth And his jaws start closin with you underneath And yer flat on your belly with yer hands tied behind And you wish you'd never taken that last detour sign And you say to yourself just what am I doin' On this road I'm walkin', on this trail I'm turnin' On this curve I'm hanging On this pathway I'm strolling, in the space I'm taking In this air I'm inhaling Am I mixed up too much, am I mixed up too hard Why am I walking, where am I running What am I saying, what am I knowing On this guitar I'm playing, on this banjo I'm frailin' On this mandolin I'm strummin', in the song I'm singin' In the tune I'm hummin', in the words I'm writin' In the words that I'm thinkin' In this ocean of hours I'm all the time drinkin' Who am I helping, what am I breaking What am I giving, what am I taking But you try with your whole soul best Never to think these thoughts and never to let Them kind of thoughts gain ground Or make yer heart pound ...

On May 6th, three incredibly courageous volunteers in wet suits dove into the flooded basement together197. The divers were Alexei Ananenko, a senior reactor mechanical engineer who knew the valves’ location, and two colleagues: Valery A Bezpalov, a turbine engineer who would turn the second valve, and Boris Alexandrovich Baranov, a shift supervisor who acted as a backup/rescuer in case of an emergency, and who also carried a flashlight. They were aware of the stakes and what radiation levels were like in the basement, but were apparently promised that their families would be well taken care of if they died.198 “When the searchlight beam fell on a pipe, we were joyous,” Ananenko told the Government-controlled news agency TASS, shortly after his return.199 “The pipe led to the valves.” Their light failed moments later and the poor men had to feel their way along the pipes in darkness. Once the valves were opened, “We heard the rush of water out of the tank. And in a few more minutes we were being embraced by the guys.” With the valves open, the pressure suppression pool was drained of its 3,200 tons of water, but all three heroic men were suffering from radiation sickness symptoms even as they emerged from the water, and each soon succumbed. Or so the tale goes.200

Two nights after the Chaworth ball, Gabriel practiced at the billiards table in the private apartments above Jenner's. The luxurious rooms, which had once been occupied by his parents in the earlier days of their marriage, were now reserved for the convenience of the Challon family. Raphael, one of his younger brothers, usually lived at the club, but at the moment was on an overseas trip to America. He'd gone to source and purchase a large quantity of dressed pine timber on behalf of a Challon-owned railway construction company. American pine, for its toughness and elasticity, was used as transom ties for railways, and it was in high demand now that native British timber was in scarce supply. The club wasn't the same without Raphael's carefree presence, but spending time alone here was better than the well-ordered quietness of his terrace at Queen's Gate. Gabriel relished the comfortably masculine atmosphere, spiced with scents of expensive liquor, pipe smoke, oiled Morocco leather upholstery, and the acrid pungency of green baize cloth. The fragrance never failed to remind him of the occasions in his youth when he had accompanied his father to the club. For years, the duke had gone almost weekly to Jenner's to meet with managers and look over the account ledgers. His wife Evie had inherited it from her father, Ivo Jenner, a former professional boxer. The club was an inexhaustible financial engine, its vast profits having enabled the duke to improve his agricultural estates and properties, and accumulate a sprawling empire of investments. Gaming was against the law, of course, but half of Parliament were members of Jenner's, which had made it virtually exempt from prosecution. Visiting Jenner's with his father had been exciting for a sheltered boy. There had always been new things to see and learn, and the men Gabriel had encountered were very different from the respectable servants and tenants on the estate. The patrons and staff at the club had used coarse language and told bawdy jokes, and taught him card tricks and flourishes. Sometimes Gabriel had perched on a tall stool at a circular hazard table to watch high-stakes play, with his father's arm draped casually across his shoulders. Tucked safely against the duke's side, Gabriel had seen men win or lose entire fortunes in a single night, all on the tumble of dice.

Few grown humans can normally survive a fall of much more than twenty-five or thirty feet, though there have been some notable exceptions—none more memorable perhaps than that of a British airman in World War II named Nicholas Alkemade. In the late winter of 1944, while on a bombing run over Germany, Flight Sergeant Alkemade, the tail gunner on a British Lancaster bomber, found himself in a literally tight spot when his plane was hit by enemy flak and quickly filled with smoke and flames. Tail gunners on Lancasters couldn’t wear parachutes because the space in which they operated was too confined, and by the time Alkemade managed to haul himself out of his turret and reach for his parachute, he found it was on fire and beyond salvation. He decided to leap from the plane anyway rather than perish horribly in flames, so he hauled open a hatch and tumbled out into the night. He was three miles above the ground and falling at 120 miles per hour. “It was very quiet,” Alkemade recalled years later, “the only sound being the drumming of aircraft engines in the distance, and no sensation of falling at all. I felt suspended in space.” Rather to his surprise, he found himself to be strangely composed and at peace. He was sorry to die, of course, but accepted it philosophically, as something that happened to airmen sometimes. The experience was so surreal and dreamy that Alkemade was never certain afterward whether he lost consciousness, but he was certainly jerked back to reality when he crashed through the branches of some lofty pine trees and landed with a resounding thud in a snowbank, in a sitting position. He had somehow lost both his boots, and had a sore knee and some minor abrasions, but otherwise was quite unharmed. Alkemade’s survival adventures did not quite end there. After the war, he took a job in a chemical plant in Loughborough, in the English Midlands. While he was working with chlorine gas, his gas mask came loose, and he was instantly exposed to dangerously high levels of the gas. He lay unconscious for fifteen minutes before co-workers noticed his unconscious form and dragged him to safety. Miraculously, he survived. Some time after that, he was adjusting a pipe when it ruptured and sprayed him from head to foot with sulfuric acid. He suffered extensive burns but again survived. Shortly after he returned to work from that setback, a nine-foot-long metal pole fell on him from a height and very nearly killed him, but once again he recovered. This time, however, he decided to tempt fate no longer. He took a safer job as a furniture salesman and lived out the rest of his life without incident. He died peacefully, in bed, aged sixty-four in 1987. —

The pipeline was designed to pass about a mile north of the Standing Rock Sioux tribal nation. The Energy Transfer Partners engineers planned to run the 30-inch-diameter steel pipe 90 to 110 feet under the Missouri River.31 This land was ceded to the Sioux under the 1868 Treaty of Fort Laramie, which, like some four hundred treaties the U.S. government signed with Native American communities, was promptly violated by Washington.32 The Missouri River provides the tribe’s drinking water. The area is rich in farmland, ancient burial grounds, and artifacts.

An Otter’s range can be 800 to 1,000 miles,’ Studd replies, ‘but it’s also possible to refuel in mid-air as it were, by carrying drums of fuel and piping them into the system.’ He laughs. ‘I was flying the Director – Dr Laws – back from Halley and the team was piping fuel in from the spare drums carried on board. I made the engines miss on purpose and shouted back to the crew, “Faster, you bastards”.

One. Treating one’s duty in the space force as an ordinary job: despite working with dedication and responsibility, lacking enthusiasm and sense of mission and doubting the ultimate significance of one’s work. “Two. Passive waiting: believing that the outcome of the war depends on scientists and engineers; believing that prior to breakthroughs in basic research and key technologies, the space force is just a pipe dream, and subsequent confusion about the importance of its present work; being satisfied simply with completing tasks related to establishing this military branch; lacking innovation. “Three. Harboring unrealistic fantasies: requesting to use hibernation technology to leap four centuries into the future and take part in the Doomsday Battle directly. A number of younger comrades have already expressed this wish, and one has even submitted a formal application. On the surface, this is a positive state of mind, a

Porter’s aerial palace, complete with twenty-six windows, a long exhaust pipe for steam sticking out the rear, and a giant American flag fluttering over the rudders, was designed to ride beneath an immense cigar-shaped dirigible. The engineering was lunacy, but Porter’s marketing was brilliant. He proposed dispensing entirely with the notorious jumping-off hassles along the Missouri River by launching his “aerial locomotive” from New York. The coast-to-coast trip, Porter’s calculations showed, could be made in just three days—five days if the prevailing headwinds were particularly bad that week. Porter aggressively advertised his “Air Line to California” in eastern newspapers and magazines. Amazingly, over two hundred suckers paid a subscription price of $50, which included three-course meals and wine, for the inaugural balloon hop to the gold fields. That winter, a large crowd gathered in a Long Island cornfield to watch Porter test a model of his airship. But the craft never left the ground because the steam engines were far too heavy for the balloon. The would-be Porter aeronauts, however, were the lucky ones—they never had to leave in the first place. The 125 paying passengers on the first Turner and Allen Pioneer Train were not so fortunate. The Turner and Allen expedition of 1849

As cadets, we constantly hammered, scraped and wire brushed rusting steel, before applying red lead paint. Most of the paint we used was Navy surplus or a concoction made up of fish oil, lampblack and china dryer. We found that by mixing all different color paints, we would wind up with a paint we called “Sh-t Grindle Brown.” Inventiveness was key as we repaired, replaced, and painted the State of Maine from stem to stern. This work, being in addition to our studies, consumed all of our time. How we managed to fit all of this into the time we had, is still a mystery. The conversion of the ship was labor intensive and expensive, but the U.S. Maritime Commission contributed to the Academy’s financial needs where possible. The mounting expenses remained a challenge but we didn’t give up. We never did finish the entire conversion prior to our first cruise, but one thing we managed to do was paint over the name “USS Comfort” and hand letter in her new name “State of Maine.” If you looked carefully, you could still see her previous name outlined by a welded bead, but this was a minor detail that would eventually be taken care of. Perhaps because of my experience with the letters on the front of “Richardson Hall,” the task of lettering her name and her new homeport on the stern became mine. Much of the ship’s superstructure was still covered with a sticky preservative made up of paint and crank case oil, which never really dried and indelibly got onto our working uniforms. However, from a distance, you couldn’t tell the difference and it looked all right, but more importantly it prevented further rusting. One bulkhead at a time, using a mixture of gasoline and paint remover, we scraped the gunk off and repainted it. The engineers had been busy rebuilding the pumps and generators, as well as repacking steam pipes with asbestos wrapping. We finally got the ship to where we could sail her to Portland under her own power. The twin Babcock and Wilcox heater-type boilers had to be repaired and re-bricked there. After this, we would continue on to the dry dock in Boston for additional work and the hull inspection that was required below the water line.

Then there is Roman engineering: the Roman roads, aqueducts, the Colosseum. Warfare, alas, has always been beneficial to engineering. Yet there are unmistakeable trends in the engineering of the gamgster states. In a healthy society, engineering design gets smarter and smarter; in gangster states, it gets bigger and bigger. In World War II, the democracies produced radar and split the atom; German basic research was far behind in these fields and devoted its efforts to projects like lenses so bog they could burn Britain, and bells so big that their sound would be lethal. (The lenses never got off the drawing board, and the bells, by the end of the war, would kill mice in a bath tub.) Roman engineering, too, was void of all subtlety. Roman roads ran absolutely straight; when they came to a mountain, they ran over the top of the mountain as pigheadedly as one of Stalin's frontal assaults. Greek soldiers used to adapt their camps to the terrain; but the Roman army, at the end of a days' march, would invariably set up exactly the same camp, no matter whether in the Alps or in Egypt. If the terrain did not correspond to the one and only model decreed by the military bureaucracy, so much the worse for the terrain; it was dug up until it fitted inti the Roman Empire. The Roman aqueducts were bigger than those that had been used centuries earlier in the ancient world; but they were administered with extremely poor knowledge of hydraulics. Long after Heron of Alexandria (1st Century A.D.) had designed water clocks, water turbines and two-cylinder water pumps, and had written works on these subjects, the Romans were still describing the performance of their aqueducts in terms of the quinaria, a measure of the cross-section of the flow, as if the volume of the flow did not also depend on its velocity. The same unit was used in charging users of large pipes tapping the aqueduct; the Roman engineers failed to realize that doubling the cross-section would more than double the flow of water. Heron could never have blundered like this.

Grace is the first and last moving cause of salvation; and faith, essential as it is, is only an important part of the machinery which grace employs. We are saved "through faith," but salvation is "by grace." Sound forth those words as with the archangel's trumpet: "By grace are ye saved." What glad tidings for the undeserving! Faith occupies the position of a channel or conduit pipe. Grace is the fountain and the stream; faith is the aqueduct along which the flood of mercy flows down to refresh the thirsty sons of men. It is a great pity when the aqueduct is broken. It is a sad sight to see around Rome the many noble aqueducts which no longer convey water into the city, because the arches are broken and the marvelous structures are in ruins. The aqueduct must be kept entire to convey the current; and, even so, faith must be true and sound, leading right up to God and coming right down to ourselves, that it may become a serviceable channel of mercy to our souls. Still, I again remind you that faith is only the channel or aqueduct, and not the fountainhead, and we must not look so much to it as to exalt it above the divine source of all blessing which lies in the grace of God. Never make a Christ out of your faith, nor think of as if it were the independent source of your salvation. Our life is found in "looking unto Jesus," not in looking to our own faith. By faith all things become possible to us; yet the power is not in the faith, but in the God upon whom faith relies. Grace is the powerful engine, and faith is the chain by which the carriage of the soul is attached to the great motive power. The righteousness of faith is not the moral excellence of faith, but the righteousness of Jesus Christ which faith grasps and appropriates. The peace within the soul is not derived from the contemplation of our own faith; but it comes to us from Him who is our peace, the hem of whose garment faith touches, and virtue comes out of Him into the soul.

She remembers in 1940 when the city’s population had been called upon to donate all the metal objects they could spare. Married women were asked for their wedding rings. Florence’s piazzas were thus heaped with enormous piles of tarnished rusting metal objects. There was something almost touching about the slapdash poverty of the contribution. Candelabras, door handles, pipes, bits of engines, tools. It later occurred to her that these bits of waste metal would in all probability be melted down and fashioned into weapons, ammunition maybe. That the candelabra she was looking at might end up lodged in someone’s chest in the form of a bullet, someone who would never know that a household ornament of mysterious provenance would cause his death.

The example of the jet engine can help us to clear up another confusion. Science, according to many scientists, concentrates essentially on material causation. It asks the “how” questions: how does the jet engine work? It also asks the “why” question regarding function: why is this pipe here? But it does not ask the “why” question of purpose: why was the jet engine built? What is important here is that Sir Frank Whittle does not appear in the scientific account. To quote Laplace, the scientific account has “no need of that hypothesis”.29 Clearly, however, it would be ridiculous to deduce from this that Whittle did not exist. He is the answer to the question: why does the jet engine exist in the first place?

[...] the prostate gland is a miracle of bad engineering, only a moron engineer would design an organ that's prone to swelling that surrounds a collapsable pipe [09: "Why Evolution Is True" - 35m40]

{2} Neither did I but vacant seasons spend In this my scribble; nor did I intend But to divert myself in doing this From worser thoughts which make me do amiss. Thus, I set pen to paper with delight, And quickly had my thoughts in black and white. For, having now my method by the end, Still as I pulled, it came; and so I penned It down: until it came at last to be, For length and breadth, the bigness which you see. Well, when I had thus put mine ends together, I shewed them others, that I might see whether They would condemn them, or them justify: And some said, Let them live; some, Let them die; Some said, JOHN, print it; others said, Not so; Some said, It might do good; others said, No. Now was I in a strait, and did not see Which was the best thing to be done by me: At last I thought, Since you are thus divided, I print it will, and so the case decided. {3} For, thought I, some, I see, would have it done, Though others in that channel do not run: To prove, then, who advised for the best, Thus I thought fit to put it to the test. I further thought, if now I did deny Those that would have it, thus to gratify. I did not know but hinder them I might Of that which would to them be great delight. For those which were not for its coming forth, I said to them, Offend you I am loth, Yet, since your brethren pleased with it be, Forbear to judge till you do further see. If that thou wilt not read, let it alone; Some love the meat, some love to pick the bone. Yea, that I might them better palliate, I did too with them thus expostulate:-- {4} May I not write in such a style as this? In such a method, too, and yet not miss My end--thy good? Why may it not be done? Dark clouds bring waters, when the bright bring none. Yea, dark or bright, if they their silver drops Cause to descend, the earth, by yielding crops, Gives praise to both, and carpeth not at either, But treasures up the fruit they yield together; Yea, so commixes both, that in her fruit None can distinguish this from that: they suit Her well when hungry; but, if she be full, She spews out both, and makes their blessings null. You see the ways the fisherman doth take To catch the fish; what engines doth he make? Behold how he engageth all his wits; Also his snares, lines, angles, hooks, and nets; Yet fish there be, that neither hook, nor line, Nor snare, nor net, nor engine can make thine: They must be groped for, and be tickled too, Or they will not be catch'd, whate'er you do. How does the fowler seek to catch his game By divers means! all which one cannot name: His guns, his nets, his lime-twigs, light, and bell: He creeps, he goes, he stands; yea, who can tell Of all his postures? Yet there's none of these Will make him master of what fowls he please. Yea, he must pipe and whistle to catch this, Yet, if he does so, that bird he will miss. If that a pearl may in a toad's head dwell, And may be found too in an oyster-shell; If things that promise nothing do contain What better is than gold; who will disdain, That have an inkling of it, there to look, That they may find it? Now, my little book, (Though void of all these paintings that may make It with this or the other man to take) Is not without those things that do excel What do in brave but empty notions dwell.

They had to park the Jeep, load the engine parts into the dinghy, and row across the bar, so by the time they reached the Misty Day Spence was already there, leaning against the cradle, puffing on a cigarette. Mr. Jones frowned when he saw him. “How old are you?” he asked. “Sixteen,” said Spence. “Why?” “Do you know what your lungs are going to look like by the time you’re fifty?” Spence shrugged, then nodded toward the ever-present pipe that hung from Mr. Jones’s lip. “No worse than yours, I guess,” he said. Mr. Jones looked puzzled. “He means your pipe,” Denny prompted. “Yeah,” said Spence, “and don’t give me any of that crap about a pipe being not as bad as a cigarette. They’re all the same.” Mr. Jones took his pipe out of his mouth and looked at it thoughtfully. “You know,” he said, “you’ve got a point there. Kind of like the pot calling the kettle black, isn’t it?” Spence nodded. “Tell you what I’m going to do,” said Mr. Jones. “I’ll make you a little wager. I’ll bet I can give up smoking my pipe if you can give up your cigarettes.” Denny bit her lip to keep from smiling. Spence took another drag on his cigarette and stared at Mr. Jones skeptically. “Of course, if you don’t think you’ve got the willpower,” said Mr. Jones. Spence dropped his cigarette and crushed it into the ground. “I can quit anytime I want,” he said, then looked up. “But I don’t want to.” “Oh, sure,” said Denny. “That’s what they all say.” Spence looked at her and narrowed her eyes. “Who asked you?” he said. “You just don’t think you can do it,” Denny went on. “You’re afraid Mr. Jones is gonna show you up.” “Oh, yeah?” said Spence. He pulled his cigarettes out of his jacket pocket, smiled wryly at Denny, and tossed them basketball style into Mr. Jones’s trash barrel, then reached a hand out to Mr. Jones. “You got a deal, old man,” he said. Mr. Jones shook his hand and nodded, then stuck the pipe back in his mouth. “You don’t mind if I just kind of let it hang here, do you, for old times’ sake?” Spence shrugged. “Suit yourself,” he said, “as long as you don’t light up.” “I’m a man of my word,” said Mr. Jones. “No flame will ever touch this pipe again.” Spence nodded and stalked off toward the shed. Denny giggled. “You’re awful,” she said. Mr. Jones winked. “What’s awful?” he said. “I’m doing him a favor.

And to say that the citizens of those rival domains did not always see eye to eye was a bit of an understatement, because each represented the antithesis of the other’s deepest values. To the engineers and the technicians who belonged to the world of the dam, Glen was no dead monolith but, rather, a living and breathing thing, a creature that pulsed with energy and dynamism. Perhaps even more important, the dam was also a triumphant capstone of human ingenuity, the culmination of a civil-engineering lineage that had seen its first florescence in the irrigation canals of ancient Mesopotamia and China, then shot like a bold arrow through the Middle Ages, the Renaissance, and the Industrial Revolution to reach its zenith here in the sun-scorched wastelands of the American Southwest. Glen embodied the glittering inspiration and the tenacious drive of the American century—a spirit that in other contexts had been responsible for harnessing the atom and putting men on the moon. As impressive as those other accomplishments may have been, nothing excelled the nobility of transforming one of the harshest deserts on earth into a vibrant garden. In the minds of its engineers and its managers, Glen affirmed everything that was right about America. To Kenton Grua and the river folk who inhabited the world of the canyon, however, the dam was an offense against nature. Thanks to Glen and a host of similar Reclamation projects along the Colorado, one of the greatest rivers in the West, had been reduced to little more than a giant plumbing system, a network of pipes and faucets and catchment tubs whose chief purpose lay in the dubious goal of bringing golf courses to Phoenix, swimming pools to Tucson, and air-conditioned shopping malls to Vegas. A magnificent waterway had been sacrificed on the altar of a technology that enabled people to prosper without limits, without balance, without any connection to the environment in which they lived—and in the process, fostered the delusion that the desert had been conquered. But in the eyes of the river folk, even that wasn’t the real cost. To

Will it get us to Las Máquinas?" asked Thor. "Well," said Catrina, "if we replace the two flat tires –" The car backfired a few times and black smoke began pouring out of the exhaust pipe. "– and fix that –" The hood of the car popped open, then tore free of its hinges and crashed to the floor. "– and that –" The engine burst into flames. "– no." "Then I guess we're stealing a car.

Engineer’s fascination with CPVC began in the mid-1990s. During this period, in the construction and plumbing industry, pipes were still made of iron and copper. Engineer saw that corrosion was a major problem with galvanized pipes and India was materially behind the evolution curve in the use of plastics for pipes. In the United States, CPVC was the new anti-corrosion solution for plastic pipes, which was swiftly replacing metal (iron and copper) pipes in industrial applications. CPVC was also a superior product compared to PVC because of higher ductile strength, which gave it the ability to handle hot water up to 200 degrees Fahrenheit (93° Celsius) (PVC can handle hot water only up to 140 degrees Fahrenheit [60° Celsius]). B.F. Goodrich (now known as Lubrizol) held the patent for CPVC resin technology, and Engineer decided to tie up with them to bring CPVC to India. He travelled to the United States to forge a techno-financial joint venture (JV) deal with Thompson Plastics of USA, which provided Astral with the technical know-how for setting up the CPVC plant. Astral also acquired the licence for CPVC resin procurement from Lubrizol (the first Indian company to do so). With a JV partner on board and a licence in his hand, Engineer set up Astral Poly Technik in March 1996. Thompson put up 20 per cent of equity for the company and Engineer approached his uncle to fund another 20 per cent. For his personal equity contribution, Engineer sold his house in Ahmedabad. I met Engineer at Astral’s corporate office located off the bustling Sarkhej–Gandhinagar Highway and behind the prestigious Rajpath Club in Ahmedabad. Recalling those early days, Engineer told me, ‘There was a time when everything my father-in-law and I owned was mortgaged to build Astral.

Putting alerts into email and hoping that someone will read all of them and notice the important ones is the moral equivalent of piping them to /dev/null: they will eventually be ignored.

Not long ago, I attended a gathering with a congregation other than my own, and I thought my ears were going to bleed. The moment the preservice music began, the congregation collectively shuddered and stood cringing under the instrumental blast for the next thirty minutes, until the sermon began. We hoped that the volume would modulate downward after the sermon, but it didn’t. The preacher left the platform and the onslaught continued. I couldn’t resist the temptation to pull out my iPhone and use an app to check the sound levels. While the app surely isn’t the most accurate measurement, it measured sustained levels well over 110 decibels, which can be damage-inducing. (By contrast, our sound engineers at Sojourn are trained to keep sustained volume at about 90 decibels or below, at which they have varied levels of success.) The irony of this, of course, is that I was in a traditional service, and the instrument in question was a roaring pipe organ.

I will use the memory of Pipe to remind myself that I have been damaged as much as I have damaged others, and this is not a special thing. It's just the way my world works. It's been easy to believe, in this room for three months, that I have been at the centre of amazing events. But I'm a tiny part of the intricacies and engineerings of Earth. And I'm not half as clever as I once thought I was. Just as Pipe might be one of so many, I am a drop in the ocean of humanity. We move, we surge, we dash and we flow, and we think that our furious beating upon the far shores of the universe means we are powerful. But we are only the crest of an uncontrollable surge in the tide. Those who rush up from behind to replace me will be just as guilty, and as innocent, as I am. We all have no real idea of where we go, and what we do.

Better move aside, Shell. You're right where the oil should come out. Not connected to a line, so we'll just let her flow a bit." I moved aside. He freed the valve, then turned it by hand. At first it was just a trickle, then it gushed. Ed spun the valve and stepped back with a whoop, and on his face was the expression of a man looking on something he loves. "Baby, baby," he yelled, "there she goes." Oil, thick and black, spurted from the pipe like black blood from a cut artery. It streamed from the Christmas tree and spread on the ground, running in a thick river away from us down a shallow furrow in the earth. And a queer feeling gripped me. I knew, then, that until this moment I hadn't really believed it. I'd just sort of gone on faith to here, but now I could see it, touch it, smell it. Oil. Oil, growling up from deep in the earth, pushed by Nature's gases, and for one brief moment of brighter awareness I could see it, refined, split, joining in new chemical compounds — in cars, generators, lamps, diesels; driving engines and smoothing bearings; in hundreds of products with thousands of uses, from farming to photography, plastics, medicines . . . And there all the time for the man with faith enough and strength enough to find it and seize it.

I drove that yellow pickup truck for 120,000 miles—and do you know what? I never changed the oil. Not even once. This, of course, did irreparable damage to the engine. I drove down the street each day with white smoke billowing out of the exhaust pipe. I looked like Uncle Buck. Most of us will do almost anything, even foolish things, to avoid being told what it is we want. When someone tries to control us, it teaches us new ways to be dumb because it reminds us of old ways we’ve been manipulated before.

Damage to Curtiss resulted from an enemy aircraft colliding with the forward crane. The enemy plane burned on the boat deck. This occurred at 0905. Another bombing attack occurred at 0912. One bomb fell on the mooring buoy aft and two bombs fell alongside. Fragment damage from these three bombs was considerable. Another bomb struck the starboard side of the boat deck, passed through three decks, and exploded on the main deck causing considerable damage. These bombs were about 250 kilograms, measured about 12 inches in diameter, and carried about 130 pounds of TNT. They were released by dive-bombers from a height of about 300 to 400 feet. The widespread damage caused by fragments to the piping, electric wires, steam lines, and ammunition supply, etc. overshadowed entirely the structural damage which they caused. Even the after engine room was affected by fragments from the bomb hit. Many fires were started and these were difficult to extinguish due to smoldering cork insulation and poor lighting. Much of the fragment damage could have been prevented by use of some armor, which was forbidden in auxiliary vessels under the arms limitation treaties. Later designs provided two-inch splinter protection for sixty percent of the length, as well as splinter protection for gun, fire control, and ship control stations. The Navy Yard undertook repairs to Curtiss on two separate availabilities; the first was from 19 to 27 December. When replacement parts were received, Curtiss was in the Yard from 26 April to 28 May 1942. At that time final repairs were made. 9. U.S.S. HELM, DESTROYER (LAUNCHED IN 1937) We have seen how Helm got underway promptly and patrolled the waters for submarines

This feeling of irritability and alienation meant I was malleable. Have you ever tried to argue with someone who doesn’t want anything from you? It’s hard. Have you ever noticed in a row with someone that no longer loves you that you have no recourse? No tools with which to bargain. If you stroll up to a stranger and tell them that unless they comply with your demands they’ll never see you again, it’s unlikely that they’ll fling themselves at your feet and beg you not to go. They’ll just wander off. When people are content, they are difficult to maneuver. We are perennially discontent and offered placebos as remedies. My intention in writing this book is to make you feel better, to offer you a solution to the way you feel. I am confident that this is necessary. When do you ever meet people that are happy? Genuinely happy? Only children, the mentally ill, and daytime television presenters. My belief is that it is possible to feel happier, because I feel better than I used to. I am beginning to understand where the solution lies, primarily because of an exhausting process of trial and mostly error. My qualification to write a book on how to change yourself and change the world is not that I’m better than you, it’s that I’m worse. Not that I’m smarter, but that I’m dumber: I bought the lie hook, line, and sinker. My only quality has been an unwitting momentum, a willingness to wade through the static dissatisfaction that has been piped into my mind from the moment I learned language. What if that feeling of inadequacy, isolation, and anxiety isn’t just me? What if it isn’t internally engineered but the result of concerted effort, the product of a transmission? An ongoing broadcast from the powerful that has colonized my mind? Who is it in here, inside your mind, reading these words, feeling that fear? Is there an awareness, an exempt presence, gleaming behind the waterfall of words that commentate on every event, label every object, judge everyone you come into contact with? And is there another way to feel? Is it possible to be in this world and feel another way? Can you conceive, even for a moment, of a species similar to us but a little more evolved, that have transcended the idea that solutions to the way we feel can be externally acquired? What would that look like? How would that feel—to be liberated from the bureaucracy of managing your recalcitrant mind. Is it possible that there is a conspiracy to make us feel this way? If we were cops right now, we’d look for a motive. If our peace of mind, our God-given right to live in harmony with our environment and one another, has been murdered, who are the prime suspects? Well, who has a motive?

Newcomen’s engine borrowed the best features of its predecessors and incorporated new features of its own. It borrowed Huygens’s cylinder and piston but followed Papin in substituting steam for gunpowder. It borrowed from Savery the idea of condensing steam to make a vacuum. The Newcomen engine, however, unlike Papin’s or Savery’s, heated water to steam in a large, separate boiler, then piped the steam through a flap valve up to an open-ended cylinder mounted overhead. Instead of using steam pressure to push up the piston, as Papin had, Newcomen hung the piston from a massive wooden rocking beam so that the weight of the beam as it rocked pulled up the piston to open the cylinder between cycles.

Jacob couldn't really hear the sound of the other landships over the humming and cranking of his own. He heard the whistle of steam coming from the pipes and the latching of the iron tracks as they clicked into place. He heard gears adjusting, the rhythm of the pumps, the revving of the engine, and the fuming of the furnace. He also heard Andil’s heavy breathing, and he heard his own heart’s heavy beating.

It’s a well-known statistic that there are 800 burial sites around Chernobyl. He was expecting some sort of amazing engineering structures, but they were just ordinary pits. They were filled with trees from the ‘red forest’ that was cut down in a 150 hectare area around the reactor. In the first two days after the accident, pine trees turned red and then russet. There were thousands of tonnes of iron and steel, pipes, work clothes, concrete structures. He showed me an illustration from an English magazine, panoramic, from the air. Thousands of tractors, aircraft, fire engines and ambulances. The largest burial site was said to be next to the reactor. He wanted to photograph it now, ten years on, and had been promised a lot of money for the image. So there we were, being sent from one senior official to another. One said they needed a location from us, another that we needed a permit. We were just getting the run-around, until it dawned on me that this burial site did not exist. There no longer was a site in reality, only in reports. The machinery had long ago been looted and taken off to markets, to collective farms or people’s homes for spare parts. It was all gone. The Englishman could not understand that. He could not believe it. When I told him the truth, he simply could not believe it!

The ship’s electricity was produced by three turbo-drive 300 kW DC generators when at sea, but when ashore, for the most part, electricity came from either the Central Maine power grid or a generator in the Engineering Laboratory. The State of Maine was considered cold iron until her boilers were lit off, breathing life into her soul. This would be the first time the engineers fired up the boilers and cautiously brought up a head of steam close to her rated 450 psi at 759 degrees. At this temperature, a failure was not an option. The steam was so hot as to be invisible and could instantly cut a two by four in half. There have been recorded boiler and steam pipe failures resulting in the deaths of people in the engine room, so we were taking no chances! Out on the open deck the sky was sunny however the air was frigid. It was the kind of day you could expect in Maine this time of year and we were just happy that the sun was shining. Now it was up to deck force to let go of all but the forward spring lines. Slowly the ship pulled ahead and as the spring line tightened, our stern swung out into the channel. At the right moment the order was given and we backed away from the dock. It was the first time for our new TS State of Maine to get underway, and so far, everything functioned satisfactorily.

Israel provided incentives for farmers to switch to drip irrigation, in which pipes with tiny holes provide small, precisely adjusted flows of water. Ideally, drip irrigation provides water at just the rate at which it can be absorbed by plant roots. Invented by the Israeli engineer Simcha Blass, it can use half or less of the water used in ordinary irrigation to nourish the same number of plants. At the same time, drip irrigation is one of those ideas that sounds simple but is hard to accomplish in practice. To exude water in regular amounts from the holes, the water pressure must be exactly the same down the entire length of the pipe, an engineering challenge; if the pipe is underground, which maximizes contact with roots, the holes must not be susceptible to clogging by dirt or being infiltrated by water-seeking roots. The first Israeli drip-irrigation firm was established in 1966; by the 1990s, the method was being used in about half of Israel’s farms.

Drain Services: Snaking/Jetting Main Sewer Line repair Toronto The jetting and snaking services we provide can fix clogged drains and prevent damage to your home. Jetting (or hydro jetting) uses high-pressure to clear any blockages in pipe systems or blocked pipelines. We are equipped with other heavy-duty drain snake tools to clear other blockages. Our trained staff offer this service in order to fix any clogging situation before it leads to flooding or has a larger impact on your plumbing system. Drain Snaking, Roto Rooter, Drain Cleaning in Toronto In order to clear any blockage in the plumbing, the snake is sent down the drain and around the bends within the pipes. The drain snake is a flexible stiff metal cable that can extend hundreds of feet. These have a strong head at the end which is turned quickly to remove blockages or used to pull out problems in the pipes. We have snakes specialized for use in kitchens, toilets, and other drains. Using a motorized snake or an auger, it is very possible to handle tougher jobs which require drain snake rooting. These tools have strong engines that enable them to penetrate through the hardest gnarled roots of trees and allows them to destroy the buildup of hard water minerals within the plumbing. The force these machines are capable of is why it is important that a professional is the one operating them. If using a rooter yourself, for user safety, it is advised you follow all safety precautions laid out in the operator’s manual. Due to the danger these tools can be to yourself and your system though, we do recommend leaving it to professionals. Some of the Precautions to be Observed If attempting to do self-repairs to your drain system using an auger there are many considerations to keep in mind. The strength of the tool you select can damage or break any pipes that are cracked to begin with. The force that the snake applies as it moves through the pipes, not to mention the head for grinding, is not recommended on damaged pipes. Drain snakes need to be selected at the correct size to ensure that they do not get tied up with itself in the pipe because it was too small. If the snake gets stuck inside the pipe it becomes a greater expense.

Clausius reasoned as follows: Carnot had been wrong to say that all the heat flowing into an engine eventually flows out. But some does. This is not converted into work but is wasted. You can feel this if you put your hand near the exhaust pipe of your car. The warmth you sense is evidence that no matter how well engineered the system, some heat will always escape.

The day-to-day running of the Empire State Building fell to the building’s manager, Chapin L. Brown, who operated as if he were the mayor of a small town. Brown supervised about 350 service employees (full tenancy would have called for one thousand), including fire and sanitation departments and a police force, as well as elevator operators and mechanics, engineers, plumbers and pipe fitters, electricians, painters, cabinetmakers, a house smith, and a staff for the general welfare of the workers, which included a nurse.

The answer is that the coolant is forced through a device called a compressor, which is the opposite of a cylinder in a steam engine. In those, heat turns into work by making a gas expand. In a compressor, work is turned into heat by squeezing a gas. Once enough heat is added in this way to ensure the coolant vapor’s temperature is greater than that of the room, it is allowed into the condenser, a network of pipes at the back of the refrigerator. Here the vapor releases into the surroundings the heat that was in the refrigerator’s interior and the heat that was created in the compressor. Put your hand behind your refrigerator to feel that combined heat.

Thomas Edison had to invent much more than the electric light. As do all innovators of new technologies, he faced the larger problem of developing and deploying the infrastructure required to support his inventions. Behind the steam engine, a network of mines and distribution systems supplied coal for its operation. Local generating plants and networks of underground pipes sustained gas lighting. When Edison planned his direct-current system of electric lighting, not wanting to run wires as thick as a man’s leg, he envisioned neighborhood-scale generating stations—steam engines turning direct-current generators—modeling his system on the gas-lighting system and even running his wiring, like gas, in pipes underground.

He smelt of summer air and engines and pipe smoke and faraway places.

Defeatism among the troops takes the following forms: “One. Treating one’s duty in the space force as an ordinary job: despite working with dedication and responsibility, lacking enthusiasm and sense of mission and doubting the ultimate significance of one’s work. “Two. Passive waiting: believing that the outcome of the war depends on scientists and engineers; believing that prior to breakthroughs in basic research and key technologies, the space force is just a pipe dream, and subsequent confusion about the importance of its present work; being satisfied simply with completing tasks related to establishing this military branch; lacking innovation.

Understanding the Importance of Pressure Relief Valves in Industrial Systems Pressure Relief valves (PRVs) play a critical role in ensuring the safety and efficiency of industrial systems across various sectors, from manufacturing plants to chemical processing facilities. These valves are essential components designed to control or limit the pressure within a system by releasing excess pressure when it exceeds a set limit. The importance of pressure relief valves cannot be overstated, as they protect both personnel and equipment from the dangers of over-pressurization. What Are Pressure Relief Valves? A pressure relief valve is a safety device that automatically releases pressure from a system to maintain safe operating levels. It is commonly used in pressurized vessels, pipelines, and tanks where the pressure may rise beyond the acceptable limit due to unexpected changes in the system's operation or external factors. When the pressure reaches a pre-determined value, the valve opens to release fluid or gas, thus reducing the pressure and preventing potential damage or catastrophic failures. The Safety Aspect: Preventing Equipment Damage and Catastrophic Failures One of the primary reasons for installing pressure relief valves in industrial systems is to prevent damage to critical equipment. Excessive pressure buildup can cause pipes, tanks, or pressure vessels to rupture, which could result in expensive repairs, production downtime, and in the worst-case scenario, hazardous accidents. In industries where flammable or toxic materials are used, over-pressurization could lead to explosions, chemical spills, or leaks, endangering both workers and the surrounding environment. For example, in the oil and gas industry, pipelines carrying crude oil or natural gas are constantly exposed to pressure variations. A pressure relief valve ensures that, even if the pressure suddenly rises, the system remains intact, minimizing the risk of pipeline rupture or explosion. Regulatory Compliance Pressure relief valves also help industrial systems comply with regulatory standards. Organizations such as the Occupational Safety and Health Administration (OSHA), the American Society of Mechanical Engineers (ASME), and the American National Standards Institute (ANSI) enforce stringent rules on pressure management in industrial processes. These regulations mandate that systems incorporate pressure relief devices to ensure that operations are carried out safely and within regulated pressure limits. Failure to comply with these regulations can lead to costly fines, operational halts, and legal liabilities. A properly installed and functioning pressure relief valve not only helps to avoid such consequences but also ensures that industrial operations are carried out without interruption. Protecting Personnel In addition to protecting equipment, pressure relief valves are essential for safeguarding personnel working in industrial settings. Over-pressurization can lead to dangerous situations, including the release of harmful substances or the failure of protective systems. By maintaining safe pressure levels, PRVs ensure that workers are not exposed to hazardous environments or conditions that could lead to injuries or fatalities. Furthermore, the presence of a pressure relief valve in a system helps to create a more predictable and stable working environment, which is crucial for ensuring worker safety and boosting operational efficiency. Conclusion Pressure relief valves are integral components in modern industrial systems. Their ability to maintain safe pressure levels by preventing over-pressurization makes them crucial for the protection of equipment, personnel, and the environment. These valves not only ensure the longevity of industrial systems by preventing catastrophic failures but also help organizations meet regulatory standards.

hotbed of radicalism in the capital, the campus and its adjacent streets were jammed with students. Just finished with their midday prayers, they were now chanting and marching. Some were firing machine guns into the air. Charlie could feel the same violent spirit that had pervaded the scene around the embassy, and he immediately slammed on the brakes and screeched to a halt. Jamming the car into reverse, he gunned the engine and began to back up but was cut off by a VW van filled with students that had come up behind them. The VW’s driver suddenly began screaming something about their American car, and six young men jumped out, carrying wooden sticks and metal pipes. “Lock your doors, Claire,” Charlie ordered, doing the same on his side. Wild-eyed, the students surrounded the Buick, taunting and cursing them.
