Hydraulic Power Calculator

Calculate hydraulic power transferred to the liquid.

Calculator

Hydraulic power (Phyd)

Formula

The hydraulic power transferred to the liquid is calculated as:

Phyd = ρ · g · Q · H

Where:

  • Phyd = hydraulic power [W]
  • ρ = liquid density [kg/m³]
  • g = gravitational acceleration [9.80665 m/s²]
  • Q = flow rate [m³/s]
  • H = total head [m]

Engineering note

Hydraulic power does not include pump efficiency. Pump input power will be higher.
