boiler heating cycle pump power estimation method

Pump Power Calculator - Engineering ToolBox

The theoretical pump power can be calculated as. P h(kW) = (1 m 3 /h) (1000 kg/m 3) (9.81 m/s 2) (10 m) / (3.6 10 6) = 0.027 kW. Shaft Pump Power. The shaft power - the power required transferred from the motor to the shaft of the pump - depends on the efficiency of the pump and can be calculated as. P s(kW) = P h(kW) / (3) where
