Relief Capacity of Rupture disc and relief valve

  1. Aug 22, 2014 #1
    I need to compute for the relief capacity (gpm or lb/hr) of a 10" rupture disc with relief valve set at 180psig. Vented out into the atmosphere. Assume fluid is water at 140F. I tried using ASME and API Equation but they give different answers. Can someone tell me the correct answer and what equation to use. Thankd

    at 180psig, I would imagine BPVC would take precedence.

    What was the capacity you computed? Using eq. From crane i computed 10200 Klb/hr from ASME i computed 2200 Klb/hr.
