Hazen hydraulic conductivity
WebThe 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 [1] such as fire sprinkler systems, [2] water supply networks, and irrigation systems. WebThe Hazen formula relates hydraulic conductivity to the D 10 grain size (mm): (7.5) k = 0.1 × D 10 2 m / s The Hazen formula can provide reasonable approximations for relatively loose, uniform granular soils, but it does not take into consideration soil density or nonuniform gradations.
