WebTools. 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 [1] such as fire sprinkler systems, [2] water supply networks, and irrigation systems. WebUsing the formulas below, you can both calculate the water flow in the pipe, and determine the dependence of the pipe diameter on the water flow. In this water consumption formula: q is the flow rate in l / s, V - determines the speed of the hydraulic flow in m / s, d - internal section (diameter in cm). Knowing the flow rate and d of the ...
