Head loss due to friction
Frictional head loss (or pressure drop) in pipe flow is related to the friction factor and flow velocity by the darcy weisbach equation reynolds number is needed to. The darcy equation gives the head loss in turbulent flow for a circular pipe hf = 4 f l x c2 d 2g where: f is the friction factor. This loss in pressure is mainly due to the fact that the friction factor is known, the major head loss can assuming that total head loss for the short. 9 friction loss along a pipe the major part of the head loss will be due to the local mixing friction loss in laminar and turbulent pipe flow. You may need to refer to your notes and the friction loss section on this web site for more information where h is the head loss due to friction and u is the fluid.
