Consider a pot of boiling water maintained at a constant level of 1,000 gallons by the addition of tap water. If the tap water used for makeup contains 1 lb. of solids in every 1,000 gallons, and initially the pot is filled with 1,000 gallons of tap water, the system water is said to be at 1 cycle. This is because no evaporation has occurred yet.

Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate. Using the Steam Property Calculator, properties are determined using Steam Pressure and Quality = 0 (Saturated Liquid). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Blowdown Energy Flow = Specific Enthalpy * Mass Flow.
