WebHead Loss Friction head loss or drop in pressure in a pipeline is an everyday concern for the water works engineer. Head loss calculations are based on equations developed by hydraulic engineers who conducted numerous flow tests on in-service water mains. Several formulas were developed by Darcy, Chezy, Cutter, Manning, Hazen-Williams, and others. WebHead Loss Correlations (1) For turbulent ﬂow the dimensional form of the equation for pressure drop is ∆p = φ(V,L,D,µ,ρ,ε) where ε is the length scale determining the wall roughness.

WebNov 28, 2024 · The head loss is a function of velocity squared and the friction factor. For laminar flow, the friction factor varies linearly with 1/Re, so the head loss (or pressure drop) varies linearly with velocity, just as the OP surmised. For turbulent flow, the relationship is more complicated. WebCalculations.
