WebA 125 mm pipe has a friction loss of nearly 33 m per 1000 m and a 150 mm size of pipe, 13 m per 1000 m. ∴ Total frictional head for a 125 mm pipe. and for a 150 mm pipe. A friction loss of 37.125 m in a total length of 1000 m is quite high and will require a larger motor. 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:
