Abstract: In the design of a water main network, one commonly used practice to simplify the calculations is to replace a certain nunber of network pipes with a single hydraulically equivalent pipe. Many excellent techniques and nomographs have been published for calculating the length of the equivalent pipe. This paper presents general equations for calculating equivalent pipe length by using three popular steady flow equations: Hazen-Williams, Manning, and Darcy-Weisbach.
