Hey Guys,
When calculated relief load for the fire case of a tank full of vapor, do you need to convert ACFM to SCFM (most valve manufacturers have their capacities in SCFM). Or can you convert the capacity in SCFM to lbs/hr and compare to your calculated load (API 521 calculation gives lbs/hr). So the relief situation is 800 Rankine and 150 PSIG.
Thanks.
