Professional engineering calculators for pump selection, system design, and performance analysis. Get accurate results for flow rates, head calculations, power requirements, and more.
Calculate required flow rate based on fixture units, population, or process requirements.
Calculate total system head including static head, friction losses, and minor losses.
Calculate hydraulic power, brake horsepower, and motor requirements.
Calculate Net Positive Suction Head Available and compare with required NPSH.
Determine required pump capacity based on your application type. Residential calculations use population and per-capita consumption, while commercial uses fixture units and building type factors.
Calculate total system resistance including static lift, pipe friction, and fitting losses. Accurate head calculations are critical for proper pump selection.
Estimate power requirements and operating costs. Includes pump and motor efficiency factors to determine actual power consumption and annual energy costs.
Verify adequate Net Positive Suction Head to prevent cavitation. Compare available NPSH with pump requirements and ensure sufficient safety margin.
Our calculators provide initial estimates, but every application is unique. Get expert engineering consultation for complex systems and critical applications.
