FAQ
Pump Head Calculator questions
Can I use different units?
Yes. Select the unit beside each input. The calculator converts values internally before solving.
Are these results suitable for final design?
Use results for education, screening, and early design checks. Verify final work against standards, codes, and project requirements.
Why do fluid results depend so much on assumptions?
Fluid calculations depend on geometry, roughness, density, viscosity, coefficients, and flow regime. Use representative input values and confirm assumptions.
