Hazen williams formula in si units
WebIn 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. where: V is velocity (in ft/s for US customary units, in m/s for SI units) WebAn alternative way to determine friction loss in straight pipes is to use the Hazen-Williams equation. It has the advantage that the factor C is independent of the Reynolds Number and consequently the cumbersome procedure of determining the friction coefficient is avoided.
