How to Use the Pump Efficiency Calculator

  1. Enter the flow rate (Q) in cubic meters per second (m³/s).
  2. Enter the head (H) in meters (m).
  3. Enter the power input (P) in kilowatts (kW).
  4. Click the "Calculate" button to compute the pump efficiency.
  5. The pump efficiency (η) will be displayed as a percentage.

Working Principle

The pump efficiency is calculated using the formula:

η = (Q * H * 9.81) / (P * 1000)

Where:

  • η = Pump Efficiency
  • Q = Flow Rate (m³/s)
  • H = Head (m)
  • P = Power Input (kW)

This formula helps in determining how efficiently the pump is converting input power into useful work.
