Hydraulic pump power

Hydraulic pump power with explicit inputs, units and reproducible calculations.

Inputs

• Flow (L/s)
• Added head (m)
• Fluid density (kg/m³)
• Gravity (m/s²)
• Overall pump efficiency (%)

Assumptions and limitations

Steady incompressible flow. Supplied total head and efficiency; no pump curve, motor sizing margin, NPSH or system design.
