GBT, that is correct, basically to verify that the drop though the inlet side of the PRD was no more than 3% compared to the MAWP indicating lack of flow which could cause chatter or cause too much build up in the vessels under fire conditions where it can't relieve fast enough.
Thank you everyone for your input, i will go over the information that you have given me to help design my calculations. 1503 it does make sense as to why the valve starts to chatter. I am new to the engineering world and I am thankful for all your help. Just for clarification for everyone...
Thank you, that clarified it up a bit better than the CGA S-1.3 -2020 document I have been working with. They go about calculating it slightly different. I have all the necessary information for the valve and pressures, 3738 SCFM of valve and MAWP-5500 psi, with an assumed OP of %10 percent, I...
Good morning,
I am working on verifying a pressure relief system for NG cylinders with a Spring loaded safety device set to 5000 psi. I may be over thinking this but the jist of the problem I am having is that the piping leading to the safety valve is of 3 different sizes.
