Webη m = mechanical efficiency. P = power transferred from the motor to the shaft (W) P l = power lost in the transmission (W) Volumetric Loss and Volumetric Efficiency. Due to leakage of fluid between the back surface of the impeller hub plate and the casing, or through other pump components - there is a volumetric loss reducing the pump efficiency. WebSep 16, 2024 · Efficiency describes how well a machine can convert one type of energy into another. Suppose a machine is provided a unit of energy, and its output is half that amount. In this case, its efficiency is 50%. As well, if a pump has 100 percent efficiency, the mechanical power input equals the water power output by the pump.
