The Hazen–Williams equation is an empirical relationship which relates the flow of water in a pipe with the physical properties of the pipe and the pressure drop caused by friction. It is used in the design of water pipe systems such as fire sprinkler systems, water supply networks, and irrigation systems. It is … See more 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 … See more • Darcy–Weisbach equation and Prony equation for alternatives • Fluid dynamics • Friction See more • Engineering Toolbox reference • Engineering toolbox Hazen–Williams coefficients • Online Hazen–Williams calculator for gravity-fed pipes.
