Pipe Networks Analysis Using A New Technique (Dept.C)

This research paper exhibits the use of both Linear Theory Method (LTM) and Extended Linear Graph Theory (ELGT) to derive a new technique which could be used for the analysis of pipe networks. This study differs from other linear theory methods in the system formation of linear equations and solution procedures. The solution algorithm used in this study is independent on initial pipe flows estimation, where a power law equation is used to update the pipe flows in successive iterations. The proposed method has been extended to deal with complex systems including control devices such as pumps, pressure reducing valves (PRVs), pressure sustaining valves (PSVs), and check valves (CVS). A FORTRAN program, named SFLOW, has been written for analyzing pipe networks using this new formation of system of linear equations. To check the reliability of the proposed method, the model has been verified with EPANET algorithm against a hypothetical pipe network.
