Pump sizing calculation is based on the water a process needs and the resistance of the route. To size a pump, put those inputs and then pick horsepower. The worksheet below constructs a clean water duty point, shows all assumed…

Updated: August 30, 2026 A water tank volume calculator is a geometry and volume conversion tool that translates internal tank dimensions into cubic metres, litres, and US gallons. That geometric result is just the beginning. Defensible storage sizing must also…

Updated August 2026 A friction loss formula is a calculation that converts resistance inside a pipe into head loss or pressure drop. For ordinary water service, the two formulas you will see most often are Darcy-Weisbach and Hazen-Williams. Darcy-Weisbach starts…

The pump efficiency formula is useful hydraulic output power divided by input power, multiplied by 100%. The arithmetic is short. The important part is choosing the right input boundary: shaft power for the bare pump, or electrical power for the…

Updated August 2026 A friction loss calculator is a tool that estimates the energy a flowing liquid loses as it moves through pipe. This one returns straight-pipe major head loss in feet from four known inputs: US gallons per minute,…

Updated August 2026 Tons of refrigeration to kW refers to converting a heat-removal rate from refrigeration tons into kilowatts. One ton of refrigeration equals 3.516853 kW of cooling capacity. To convert tons of refrigeration to kW, multiply the TR value…

Updated August 2026 BTU/hr to kW is a power-unit conversion that expresses the same heat-transfer rate in two measurement systems. To convert btu/hr to kw, multiply the BTU per hour value by 0.0002930710701722222. For example, 12,000 BTU/h equals 3.5168528421 kW,…

To convert kW to hp, multiply kilowatts by 1.34102209 for mechanical horsepower. For example, a 7.5 kW rating is 10.0577 mechanical hp. The arithmetic is exact enough for documentation, but it does not by itself select a motor or prove…

Quick answer. Pump deadhead is a zero-delivered-flow condition in which a centrifugal pump keeps running against a closed or blocked discharge. The impeller still moves liquid inside the casing, but useful flow can’t leave. Shaft input is then dissipated through…

This pipe flow calculator is a conditional conversion tool that relates a stated volumetric flow rate, a stated cross-sectional area, and an average velocity. Its result remains limited by the input record: it cannot, by itself, verify a field measurement,…
