Idealized hydraulic pump input power
Estimate pump input power for a stated density, flow, head, and overall efficiency.
Method and scope
Pinput = ρgQH/η.
Use idealized hydraulic pump input power for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.
Inputs- Fluid density — kg/m³
- Volumetric flow — m³/s, L/s
- Total head — m, ft
- Overall efficiency — 1
SOURCE AND LIMITS
Assumptions: Head is the total energy head delivered to the fluid. Efficiency is an entered decimal percentage for the complete pump set. Standard gravity is used.
Limitations: Actual input depends on operating point, wear, fluid, installation, and efficiency definition.
