WebHazen-Williams Equation: V = k C (D/4) 0.63 S 0.54 where S = h f / L and Q = V π D 2 / 4. k is a unit conversion factor: k=1.318 for English units (feet and seconds). k=0.85 for SI … WebThe Hazen-Williams equation stems from using empirical methods in predicting head loss in a water pipe when flow is turbulent. Before the advent of more sophisticated models such as Darcy-Weisbach, the use of Hazen-Williams was predominant amongst engineers.
WebThe Hazen-Williams equation is used widely in water supply and sanitary engineering. This equation uses a constant, the Hazen-Williams C, to indicate the roughness of a pipe interior. Because of the empirical nature of the equation, its range of applicability is limited.
