Title: Analysis & Design of Water Networks Systems Using Finite Element Method
Author: Hassan Abdel Mageid, Ibrahim
Abstract: Water distribution network analysis is usually interpreted as providing a need for an deficient technique to compute the pressures in a defined network at defined levels of consumption. The analysis has received considerable attention recently. This is almost entirely due to the existence of digital computers which make tedious, iterative calculation more amenable to a quick solution. In addition, obtaining a solution to these problems has important economic and design significance, especially in developing countries like ours, Several authors {9,13,31} have described many .sophisticated methods and many computer programmes have been written to solve pipe network problems. Yet most design engineers in Sudan are still using the Hardy Cross method. This is because these programmes were either developed for special networks, or use sophisticated algorithms and need large computers with large storage capacity for their implementation. In this research, a simple and efficient computer programme, based on the Finite Element method, is introduced. The programme was applied successfully to the .solution of three different networks. In order to demonstrate the feasibility of the approach and to show some merits and demerits of the finite element method ,a comparison was made on a digital computer with the standard Hardy Cross method .In all cases the finite element method is shown to provide superior performance, An extension design has been made. A trial and error approach with pipe sizes being varied until satisfactory criteria (stress, pressure ,and velocity ) were achieved . Also the programmes were performed on three different machines (Wang vs 100, Apple lle, IBM micro-computer) to show the effect of increasing storage capacity, machine accuracy, and time saving.
