WebbGeneral form. 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 … WebbThe head loss (or the pressure loss) due to fluid friction (H friction) represents the energy used in overcoming friction caused by the pipe walls.
