Calculation

P = Δp · Q

High pressure and high flow increase fluid power; pump efficiency is applied afterwards.

Understand the inputs
  • Fluid power P — Ideal useful power in the fluid.
  • Pressure difference Δp — Difference between inlet and outlet pressure.
  • Volumetric flow Q — Fluid volumetric flow.
Example

10 bar · 6 l/min = 100 W.

Assumptions and limits

Steady incompressible estimate; efficiency and compressibility are excluded.
