Pipe network analysis is the analysis of the fluid flow through a network that containing several interconnected branches of pipes and their components. The common analysis of pipe network often demonstrates to determine the flow rates and pressure drops in the individual components of the pipe network. Water utilities typically use specialized software to solve these issues automatically. Municipal water systems frequently route water through a water supply network to reach a large number of users. In this paper we aim to demonstrate the use of WaterCAD software to solve hydraulic design parameter of an example pipe network problem.
