How to use this calculator
- Enter the flow rate (L/min) and pressure (bar).
- Add efficiency for the input power.
How it works
Hydraulic power (kW) ≈ flow(L/min) × pressure(bar) ÷ 600, divided by efficiency.
Worked example
20 L/min at 150 bar. = 5 kW (at 100% efficiency).
Common mistakes
- Forgetting efficiency — input power is higher than output.
- Mixing units — use L/min and bar for this formula.
Frequently asked questions
Is this input or output power?
At 100% it's the hydraulic (output) power. Enter a real efficiency to estimate the input (motor) power.
