WebThe Hazen-Williams Coefficient (C) fluctuates between around 60 and 160. The greater the coefficient, the smoother the pipe. C is dependent upon several elements; e.g., internal conditions on the pipe's surface, pipe age, and the effect of heat and chemical exposure over time. The coefficient will vary over a pipe's lifetime; as such, informed ...
