WebHazen-Williams Equation for Pressure Loss in Pipes Imperial Units Specified Data l = length of pipe (ft) c = Hazen-Williams roughness constant q = volume flow (gal/min) dh = inside or hydraulic diameter (inches) Calculated Pressure Loss f = friction head loss in feet of water per 100 feet of pipe (ft H20 per 100 ft pipe) Henri Pitot discovered that the velocity of a fluid was proportional to the square root of its head in the early 18th century. It takes energy to push a fluid through a pipe, and Antoine de Chézy discovered that the hydraulic head loss was proportional to the velocity squared. Consequently, the Chézy formula relates hydraulic slope S (head loss per unit length) to the fluid velocity V and hydraulic radius R:
