How is the power of the pump shaft calculated?
Input power refers to the power absorbed by a device. For an electrical device, the input power is equal to the product of the input voltage at the input current. For different devices, the input power has different interpretations. For example, the speaker's input power refers to the power of the unit in the speaker, the power of the unit in the speaker.
The pump shaft power is the net power of the actual pump input. In layman's terms, the power of the motor to the pump. If other factors are not considered, the pump shaft power = the input power of the motor * the efficiency of the motor.
Efficiency (efficiency) refers to the ratio of useful power to driving power, and also brings many meanings. Efficiency is also divided into many kinds, such as mechanical efficiency (mechanical, efficiency), heat efficiency (thermal, efficiency) and so on. Efficiency is not directly related to the speed of doing work.
