WebThe 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. C = a constant for internal pipe roughness. 150 is the commonly accepted value for PVC and CPVC pipe. WebStudies have shown that PVC pipe has an initial Hazen-Williams “C” value of 155-165 that may decrease to 150 over the life cycle of the pipe. DIPRA uses a “C” value of 150 for …
Webthere is no decline in the “C” factor: “Cement-mortar lined Ductile Iron Pipe provides a Hazen-Williams flow coefficient, or “C” value, of 140 — a realistic value that is maintained over the life of the pipe.”However, closer inspection of the test data used in their publication shows that there is a decline over time: WebQuestion: Using the Hazen-Williams equation, determine the minimum diameter of a new cast iron pipe (C-130) for the following conditions: the upstream end is 51.8 m higher …
