Web52 rows · Hazen-Williams Coefficients Table. The Hazen–Williams equation has the … WebThe Hazen–Williams equation is an empirical relationship which relates the flow of water in a pipe with the physical properties of the pipe and the pressure drop caused by friction. It is used in the design of water pipe systems [1] such as fire sprinkler systems, [2] water supply networks, and irrigation systems.
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., … WebJul 13, 2016 · In the case of using the Hazen-Williams equation, if you enter an adjustment multiplier of 0.7 for example, a pipe whose H-W C was entered as 130, will be 130*0.7=91 in the calculations.
