2014-7-3 · h f is related to the Fanning friction factor f through 2 f 2 LV hf Dg = or alternatively we can write the pressure drop as . 2 (2) L Pf V D ρ ∆= Friction Factor . In laminar flow, 16 Re f = . In turbulent flow we can use either the Colebrook or the Zigrang-Sylvester Equation, depending on the problem. Both give equivalent results within ...
