Mar 17, 2015 · Feedwater Mass Flow = Steam Mass Flow / [ 1 - Blowdown Rate ] Using the Steam Property Calculator, properties are determined using Deaerator Pressure and Quality = 0 (Saturated Liquid). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Feedwater Energy Flow = Specific Enthalpy * Mass Flow.
