Here is how the Mechanical efficiency(%) calculation can be explained with given input values -> 80 = (8/10)*100.

FAQ

What is Mechanical efficiency(%)?
The Mechanical efficiency(%) formula is defined as the ratio of actual torque to the theoretical torque multiplied by hundred and is represented as ηm=(Tact/Tth)*100 or Mechanical efficiency =(Actual torque/Theoretical torque)*100. Actual torque is the actual value of torque supplied to the pump and Theoretical torque is the theoretical value of the torque developed by the pump.
How to calculate Mechanical efficiency(%)?
The Mechanical efficiency(%) formula is defined as the ratio of actual torque to the theoretical torque multiplied by hundred is calculated using Mechanical efficiency =(Actual torque/Theoretical torque)*100. To calculate Mechanical efficiency(%), you need Actual torque (Tact) and Theoretical torque (Tth). With our tool, you need to enter the respective value for Actual torque and Theoretical torque and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Mechanical efficiency ?
In this formula, Mechanical efficiency uses Actual torque and Theoretical torque. We can use 2 other way(s) to calculate the same, which is/are as follows -
  • Mechanical efficiency =(Theoretical torque/Actual torque)*100
  • Mechanical efficiency =(Specific Weight*(Discharge+Leakage of liquid per second)*(Velocity of whirl at outlet*Tangential velocity of impeller at outlet/[g]))/Input Power
