Frequently Asked Questions
Common questions about Water Pressure Drop Calculator, formulas, and expected usage.
What method is used to estimate pressure drop?
This calculator uses a Hazen-Williams based approximation, commonly applied to water flow in building piping.
Why does smaller pipe increase pressure drop?
Smaller inside diameter increases velocity and friction effects, producing higher pressure loss at the same flow.
What does the C-factor represent?
The Hazen-Williams C-factor models pipe roughness, where higher C values indicate smoother pipe and lower friction loss.
Is this suitable for final engineering design?
Use it for preliminary sizing and comparisons. Final designs should follow code, manufacturer data, and complete hydraulic calculations.
