Hazen-williams equation for pipe flow
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. http://www.zonums.com/online/engineering/hazen_williams_eq
