WebFriction head loss or drop in pressure in a pipeline is an everyday concern for the water works engineer. Head loss calculations are based on equations developed by hydraulic engineers who conducted numerous flow tests on in-service water mains. Several formulas were developed by Darcy, Chezy, Cutter, Manning, Hazen-Williams, and others. WebFriction Loss Through Pipe The Hazen-Williams equation below is widely used to calculate friction loss for water through PVC and CPVC pipe f = .2083 x (100)1.852 x G1.852 C di4.8655 Where: f = friction head of feet of water per 100' for the specific pipe size and I.D.
