Three calculations you can reproduce
Follow the inputs, equations and checked results, then use the free calculators to try your own conditions. These are illustrative engineering cases with explicit assumptions.
Multi-Section Pipe Pump Head: Worked Example
Calculate pump head through two pipe sizes, fittings, a heat exchanger and a 5 m rise. Follow the pressure breakdown and download the example.
Pipe Size vs. Pressure Drop: Worked Example
Compare 1½, 2 and 2½ inch Schedule 40 pipes at 10 m³/h. See velocity, friction loss and head, then reproduce each case in the calculator.
NPSH Available: Open-Tank Worked Example
Calculate NPSH available for a pump above an open tank. Compare normal level, low level and increased suction losses using absolute pressures.
