WebThe Darcy-Weisbach equation was difficult to use because the friction factor was difficult to estimate. In 1906, Hazen and Williams provided an empirical formula that was easy to use. The general form of the equation relates the mean velocity of water in a pipe with the geometric properties of the pipe and slope of the energy line. Webequations for calculation friction factor is given in [7]. 2. HAZEN-WILLIAMS EQUATION AND ITS LIMITATIONS When pressure drop estimations in water-carrying pipes are observed, one of the most widely used empirical equations for pressure drop is Hazen-Williams equation, which is written in the form [8] 1,852 4,87 10.67 1,852 C D L Q g p h f f
