Hydraulic Efficiency Calculator: Pumps & Fans

Calculate Pump and Fan Hydraulic Efficiency

Watts (W)
The useful power transferred to the fluid by the pump or fan.
Watts (W)
The mechanical power supplied to the pump or fan shaft.

Results

Hydraulic Efficiency (ηh):

Unlock optimal performance with our Hydraulic Efficiency Calculator for pumps and fans. Quickly determine the energy conversion effectiveness of your fluid systems by inputting power delivered to the fluid and mechanical power input. Essential for engineers, students, and anyone optimizing hydraulic or ventilation systems.

Formula:

The hydraulic efficiency (ηh) of a pump or fan is calculated as the ratio of the power delivered to the fluid (Pout) to the mechanical power input to the shaft (Pin), typically expressed as a percentage:

ηh = (Pout / Pin) × 100%

  • Pout: Power delivered to the fluid (e.g., in Watts).
  • Pin: Mechanical power input to the pump or fan shaft (e.g., in Watts).
  • ηh: Hydraulic Efficiency (in %).
