Your estimate
Required head212.8 m
Hydraulic power6.67 kW
Design shaft power9.40 kW

This is a preliminary sizing estimate. A qualified engineer must verify NPSH, temperature, flashing, control valve losses, materials, and code requirements.

How it works

Head = pressure rise ÷ (density × gravity). Hydraulic power = density × gravity × flow × head. Shaft power divides by efficiency.

Before you use this result

Use the estimate as a planning checkpoint, not as a substitute for a project specification or professional review. Enter measurements in the units shown, keep assumptions visible, and compare the result with a supplier quote, official scoring guide, or engineering design basis where appropriate.
