Fanning Friction Factor - Pipe Flow
Fanning Friction Factor The frictional head loss in pipes with full flow may be calculated by using the following formula and an appropriate Fanning friction factor. hf = f f (L/Rh) x (v 2/2g) where: hf = head loss (m) f f = Fanning friction factor L = length of pipe work (m) Rh = hydraulic radius of pipe work (m) v = velocity of fluid (m/s)
