I am having trouble calculating the mass flow rate of saturated steam through a gate valve. Inlet and outlet pressures and properties (density, enthalpy etc.) are known along with orifice size (full open gate valve). I cannot figure out, however, the proper equation to use in the calculation of the mass flow. My old fluids book (Perry's as well) only deals with compressibility of perfect gases. Saturated steam is definately not a perfect gas. Choked flow is also not a factor (dealing with low pressures - 50 psia inlet / atmospheric outlet).
Any direction is greatly appreciated!
