WebThe head loss due to friction is given by the Darcy-Weisbach equation h L = f L D V2 2g (5) where f is the Darcy Friction Factor. For fully-developed, incompressible lami-nar flow in a round pipe f lam = 64 Re. (6) The friction factor for turbulent flow in smooth and rough pipes is correlated with the Colebrook equation 1 √ f = −2log 10 ... WebAug 19, 2015 · The Darcy-Weisbach equation is used to calculate the frictional pressure losses in pipes transporting incompressible fluids. This equation uses a dimensionless Darcy friction factor, also known as the Moody factor, to account for the relative roughness of the pipe surface.
