# Steam - Flow vs. kW Rating

## Calculate steam flow rate vs. kW rating.

Steam flow rate when kW rating is known can be calculated as

ms = 3600 P / he                                     (1)

where

ms = steam flow rate (kg/h)

P = load in kW (kW)

he = specific enthalpy of evaporation of steam at working pressure (kJ/kg)
