| Abstract | ||||
| Hydraulic friction loss in pipelines directly affects pipe and pump sizing as well as the hydraulic balance of networks. The turbulent behaviour of flowing water is highly complex because it is not predictable fully by mathematical operations based on properties of water and fundamental physical laws. All friction head-loss equations have an uncertainty in the estimation of pipe interior surface roughness. The study attempts to find the most reliable equation to determine the head loss from the most widely used pipe friction equations and examines the accuracy of friction factor in Hazen-Williams (H-W), Manning (Mn) . Chezy (Ch), Scobey (Sc), and Darcy-Weisbach (D-W) equations. | ||||
