Calculation detail

Formula: P = ρgQH / η

Hydraulic power is based on water density; input power accounts for the specified pump efficiency.

FORMULA VERIFICATION

Units, scope and reference

Reference: Hydraulic-power relation P = ρgQH/η; manufacturer curves govern selection.

Internal unit basis: kg/m³, m/s², m³/s, m. Outputs: kW.

Valid conditions: Positive flow/head; 0 < efficiency ≤ 100%.

Limitations: Water density only; no NPSH, system curve or motor efficiency.
