WebJun 21, 2024 · The Hazen–Williams equation is an empirical formula used to calculate water's velocity in a gravity-fed system. In contrast to Darcy–Weisbach's equation, Hazen–Williams has the advantage that it doesn't require an iterative calculation or guessing the friction factor or Reynolds' number. WebA Few Things to Consider to Reduce Pipe Friction Loss. Reduce the length of piping. Increase the diameter of the piping. ... Hazen-Williams Equation: V = k C (D/4) 0.63 S 0.54 where S = h f / L. Where: V = velocity k = a conversion factor for the unit system (k = 1.318 for US customary units, k = 0.849 for SI units)
