Pump Hydraulic Power Calculator

Calculate fluid hydraulic power (absorbed power) delivered to liquid by a centrifugal or positive displacement pump.

💡 Engineering Knowledge PrimerHydraulic Power represents the net useful energy imparted to fluid per unit time by a pump impeller. It is directly proportional to mass flow rate, total dynamic head, and liquid specific gravity.
CALCULATION SCOPE — Deterministic calculation within the published assumptions. Independently verify all design decisions and project-specific code requirements.
