Design of a software tool for analyzing water looped networks by linear theory

Introduction: Analyzing water looped networks lead to spontaneous solving of some linear andnon-linear equations. So repeating methods must be used. The goal of this study was to design asoftware tool for analyzing water looped networks by linear theory.Materials and Methods: The software has been written in Delphi programming language andprocess of calculation is as following: (1) forming independent linear equations of discharge in nodesof network, (2) forming approximate linear equations head loss in network loops, (3) simultaneoussolving of total linear equations and approximate linear equations, (4) repeated forming linear headloss with closer approximate by result of solving equations, and (5) repeating stage three and four tillstabilization results quantity of solving equations.Results: This software is able to solve the network with following specifications: (1) it doesn’t haveany limitation in view point of the number of water network loops, (2) the looped networks consistingsome sources, and (3) the networks containing pumps for increasing potential energy.Conclusion: Some networks with different characteristics such as the number of loops formingnetwork, network with some sources and the networks containing pumps were analyzed by thissoftware with hardy - cross methods and same results were obtained that these results are the evidencefor proper work of this software. This software is not able to solve the networks containing pressurerelief valves and checks valves and can get complicated in future.
