Pretty soon they'll bring back press gangs and the lash.
Undersized power plants that are running to hard to keep up with the load
"Keith said he didnt quite understand the intercoolers.
Thats all right, said the chief engineer patiently. The cold river water comes in here from the main, picks up heat, and comes out here, and back into the river. The oil comes in here, and goes out here, a whole lot cooler.
Keith said he understood that. What puzzles me is the heat transfer balance, he said. I take it that the hydraulic fluid goes into the intercooler at a hundred and ten degrees? Thats the maximum temperature you work at?
Thats so, said the chief engineer. In the case of the biggest motors that would be the outgoing temperature.
And it goes into the power generator about eighty degrees?
More or less.
Keith stared at the drawing, still puzzled. Well, whats the temperature rise in the cooling water, then?
The chief engineer glanced at his aide. Mr Monnington said, Fifty degrees. Fifty-five under extreme conditions.
Puzzled, Keith said, It cant go higher than the temperature of the oil, or it couldnt do any cooling. Whats the inlet temperature of the water?
Fifty degrees, said Mr Monnington. Emmanuel stirred, but left the talking to Keith.
That seems on the cold side for summer temperature, said Keith.
Its general in these rivers, said the engineer. Maybe you dont get the same conditions in England. This is snow water, made by melting the eternal snows upon the Glacier Peak.
Emmanuel leaned forward on the table. Thats baloney, he said candidly. Flume River doesnt rise from Glacier Peak. Flume River rises in the Troublesome Mountain, not much higher than five thousand feet. All the snows gone from Troublesome by the end of April, most years. He paused, and then he said, Tell you sumpn. I went fishing up the Flume two years ago, in August, ten or fifteen miles above the Eight Mile Cut. Trout fishing. We didnt catch anything because the water was too hot, the fish wouldnt stir. So there was only one thing to be done, see? We stripped off, n went in for a swim. Real warm it was I stayed in half an hour or more. I guess the water in that river, in the Flume, the one were talking of I guess it was seventy-five degrees or more, that day.
There was a dead silence in the conference room of Ferris Hydraulics, Inc."

It seem like back in the day of "The Sun Never Sets on the British Empire", some poor seaman was logging the surface temperature of every ocean they sailed. Too bad no one thought to look it up!"

Are they cooling oil? Oil is still happy at +220 F. Seawater/turbine plant cooling exchanger may be undersized.
How do they plan to operate with all the Global Warming? /s
Now the time has come to talk of shoes, and ships, and sealing wax...
Depth "... Its exact maximum depth is controversial, and reports by different authors state maximum depths ranging from 3,750 m to 4,384 m. Mean (average) water depth of the Gulf is ~1,615 m (Turner, 1999) and the basin contains a volume of 2,434,000 cubic kilometers of water (6.43 * 1017 or 643 quadrillion gallons). ..."
You missed it by (approx.) 0.9724459 MILES, which is less than one full mile, but not close enough for a game of horseshoes, or the hand-grenade toss.
Has there ever been a defense contract let, with poorly defined requirements.....?
ALL OF THEM!
I’m guessing these are gas turbines. I can’t believe they aren’t equiped with heat exchangers.
The problem is evidently poorly-designed deployments.
Made in China?
“You missed it by (approx.) 0.9724459 MILES, which is less than one full mile, but not close enough for a game of horseshoes, or the hand-grenade toss.”
hmmm.. You missed it by (approx.) 8024.00000000000000 miles ....
I would reply, acknowledging that I got the wrong Gulf, but from seeing you around this forum, seeing too how much of an ass you typically are, it’s not worth the effort.

So, your original incorrect reply was intentionally snarky?
should have allowed for global warning
