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: Web(for Hazen-Williams) Q l = Flow through pipe “l” (m 3/s) N = Number of loops n = Value based on which head-loss equation used (i.e. 1.852 for Hazen-Williams) Equation 1 is essentially the sum of the head-loss in a predefined direction around a closed loop.
