The flow through the relief valve nozzle is assumed to be sonic (M = 1), adiabatic, and isentropic. If the ambient pressure is greater than the critical nozzle pressure, the flow is sub critical (M < Mc). What is Exit Velocity given Mach number and Exit Temperature? the second Mach number is "Mach 2" instead of "2 Mach" or Machs. and Accessibility Certification, + Equal Employment Opportunity Data Posted Pursuant to the No Fear Act, + Budgets, Strategic Plans and Accountability Reports.
