Steam Calculators: Boiler Calculator

Using the calculated feedwater mass flow and blowdown rate: Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate [ Blowdown Mass Flow = 9.8 klb/hr = 99.4 klb/hr * 0.099 ] Using the Steam Property Calculator properties are determined using Steam Pressure and Quality = 0 (Saturated Liquid).
