Optimization of Water Pipe Network and Formulation of Pumping Rate

다국어 초록 (Multilingual Abstract)

Minimizing water delivery costs and increasing water supply dependability are the two keyobjectives in designing and operating of water distribution systems. An analytical solution forthe best pipe diameters of a water distribution pipe network was created in this study. The rawwater was collected from a water canal and transported to a treatment plant (WTP). Thecleansed water was pushed into the water distribution network via the pumping station. Thederivative approach was used in the optimization process, and the cost functions incorporating thevarious capital and operating expenses were used. The initial diameters were adjusted toreach the least-cost diameters. The study shows that the optimum design of a pipe network(PNW) achieves saving a total cost of about 12.3% after utilizing our unique method. Theoptimal pumping rate in the PNW can also be determined using an analytical approach thatconsiders the optimum value that occurs when the minor and friction losses in the entirenetwork are at their lowest. The analytical solution for the optimum pumping rate shows arigid value of optimum pumping rate (Qopt) which is 5296.32 m3/day. On comparativeestimates, this figure is very close to that of 5,300 m3/day interpreted from the graphicalsolution, with negligible deviation. The total cost and optimum pumping rate results for theanalyzed PNW example demonstrate the correctness of the analytical solutions, reliability, anddependability of the assumptions.
