About

Pumping Power Calculator

Features
Read full description

The Pumping Power Calculator is a precision engineering utility designed for mechanical engineers, HVAC technicians, water treatment professionals, and students. It allows users to quickly and accurately determine the energy required to move fluids through a system. Whether you are sizing a new pump, evaluating an existing system's efficiency, or studying fluid mechanics, this app provides instantaneous, reliable results in a beautifully clean interface. Key Features Dual Calculation Modes: Pressure Differential: Calculate power based on direct pressure drops across the system. Pump Head & Density: Calculate power using total dynamic head and fluid density, perfect for systems moving liquids other than standard water. Universal Unit Conversion: Swap units on the fly without losing your data. Flow: m³/h, L/min, L/s, US gpm, UK gpm Pressure: bar, psi, kPa, Pa Head: m, ft Density: kg/m³, lb/ft³ Real-World Efficiencies: Input specific Pump Efficiency and Electrical Motor Efficiency percentages to go beyond theoretical physics and see exactly what your real-world power draw will be. Comprehensive Outputs: Get a complete breakdown of your system's energy requirements presented simultaneously in Kilowatts (kW) and Horsepower (hp): Hydraulic Power: The raw energy transferred directly into the fluid. Shaft Power: The mechanical power required at the pump's drive shaft. Motor Power: The total electrical power drawn from the grid.
