Hello everybody:
In case of a fire with the inlet flow on to a vessel, the PSV will "pop" open at 21% accumulation.
My question is:
* If the generation of vapour is not large open, will the PSV opening be between 121 and 100 like a modulating (if that is the right word) control valve OR
will it...
Hello:
Not really a question for this forum.
My problem is that I bought a book for my daughter (12 years old). I want her to be an engineer. God save her.
The question in the book was "Why is snow white?". My answer is "because of ice crystals, and refraction, whatever be the input light, due...
Hello:
I have an exchanger using steam as a heating medium. Steam pressure inside the exchanger is 600# psig. Steam trap outlet goes to a drum 300 feet away operating at 70 psig. Does it mean that the pressure drop is consumed by the trap or by the line and exit losses.
I am designing a PSV for...
Hello:
I have a steam condensate drum operating at 50 psig. I have designed a pump for this system where the destination pressure is also 50 psig. The discharge losses are around 30 psi (includes line pressure drop, exchanger and a control valve).
Should I design the pump for a differential...
Hello:
Somebody told me that normal temperature carbon steel piping can be used below minus 20 deg F, if the working pressure is kept below 30% of its MAWP. I cant find a reference to this in B 31.3-2000. Can somebody please point me in the right direction.
