SUMMARY
The discussion focuses on calculating the relief capacity of a 10" rupture disc and relief valve set at 180 psig, venting into the atmosphere with water at 140°F. The user encountered discrepancies between the ASME and API equations, yielding capacities of 10,200 Klb/hr and 2,200 Klb/hr, respectively. The user seeks clarification on which equation is appropriate, emphasizing that the BPVC should take precedence in this scenario. The discussion highlights the importance of selecting the correct methodology for accurate relief capacity calculations.
