Water Hammer Analysis for NAJAF-KUFA Water Supply Project

Abstract

Water hammer phenomenon in pipelines represents the complex problems that need a special treatment during network design. The required design for such systems takes into consideration the high pressures generated in pipelines and that may lead to collapse the network. In this study, a mathematical model has been prepared for Al-Najaf-Al-Kufa united water supply project. The numerical methods such as Newton-Raphson method and Gauss elimination method have been used to solve the non-linear simultaneous equations that governed with the boundary conditions and by using the characteristics method. The partial differential equations had been transformed to ordinary differential equations, by using a computer program. In this mathematical model, the values of the generated pressures was calculated with or with out control devices or to find the suitable number of control devices required for each pipeline to keep the pressure values within a tolerable limits.
