Pump shaft power equation
WebDec 17, 2011 · Shaft Design Basics. Shaft size is dictated by torque, not horsepower, but changes in horsepower and speed (RPM) affect torque, as the following equation shows: Torque (in pound-feet) = HP x 5252/RPM. Accordingly, an increase in horsepower would require more torque, as would a decrease in rpm. For example, a 100-hp motor designed … WebPump Shaft Power Calculator HP = Torque x RPM / 5252 An engine produces POWER by providing a ROTATING SHAFT which can exert a given amount of TORQUE on a load at a …
