WebThe Hazen Williams equation was developed for water pipes. Pipe roughness is accounted for using the Hazen Williams friction factor. The hydraulic radius is the ratio of pipe cross section area over pipe circumference (r/2 = ID/4). Valves, tees and other pipe fittings should be included by adding a minor loss equivalent length to the pipeline ...
