TD2K,
That's exactly the process I was going to use. I have read API 520 and several other API codebooks along with ASME code. I wanted to see if my logic aligned with someone else's that was a little more experienced than me. I just went through using API 2000 to evaluate some low pressure...
I was wondering if anybody knew how to double check the sizing of a psv on a vessel against the flow rate of a well. Take for example if a 2" PSV was rated for 8078 SCFM (AIR) could you determine if it was able to properly relieve a vessel seeing 5000 MCFD of natural gas flow.
