| Abstract | Several methods using linearized equations are presently available to find the flow distribution in pipe networks . The characteristic of these methods should be compared with one another to determine the conditions under which each method can be applied economically. This is because each of these methods, although applicable to all pipe networks, is best suited for a different set of conditions in terms of economy in CPU time and the rate of convergence . In this study, four methods namely Linear Pipe Iteration Method, Linear Node Iteration Method, Linear Accelerated Loop Iteration Method and Finite Element Method are used to analyze five different pipe networks . Field measurements were also made to ensure that these methods yielded accurate results. It was found that the Linear Pipe Iteration Method can be adopted with any network. Although it uses more computation time, especially for large networks, it converges to all level of accuracy considered in the study. Also the Node Iteration Method gives results for all conditions, except for large networks with certain level of accuracy as found from the analysis. While the Linear Accelerated Loop Method with proper estimation of correction factor can be adopted effectively for a network. The Finite Element Method has proven to be inapplicable due to slow convergence when considering a lower tolerance limit. |
