Pump Power Calculator
This calculator determines the hydraulic power (water power) and the brake horsepower (input power) required for a pump, based on fluid flow rate, total head, fluid density, and pump efficiency.
Key Inputs:
- Unit System: Select Metric (m³/hr, m, kg/m³, kW) or Imperial (GPM, ft, lb/ft³, HP).
- Flow Rate (\(Q\)): The volumetric flow rate of the fluid being pumped.
- Total Head (\(H\)): The total equivalent height the fluid is lifted, including elevation, pressure, and friction losses.
- Fluid Density (\(\rho\)): The mass density of the fluid.
- Pump Efficiency (\(\eta\)): The overall efficiency of the pump, typically given as a percentage.
Calculated Outputs:
- Hydraulic Power (\(P_{hyd}\) / Water Power): The power actually imparted to the fluid.
- Brake Horsepower (\(P_{bhp}\) / Input Power): The mechanical power required at the pump shaft, accounting for pump inefficiencies.
