DESIGN OF A LOOPED WATER DISTRIBUTION NETWORK USING NON LINEAR PROGRAMMING

Abstract

Design of water distribution network is become subject of experiment of many researchers. It is because of the distribution network cost takes major part of total network ( it is around 70 percent), .so the optimal design of water distribution network will bring the optimal design of water supply. The problem of water distribution network is non linear in nature, due to the cost pipe function and hydraulic law that are formed the problem. The problem can be formulated in Non Linear Programming approach either in D-Q formulation, D-h formulation or in Q-h formulation. Along these three formulations, the Q-h formulation giving a better performance because of optimal result is achieved in small number of iteration. In this thesis, Non Linear programming approach will be applied, with using Generalised Reduced Gradient (GRG) algorithms. Microsoft Excel Solver is used in the process of iteration. As it is applied for simple networks, Q-h formulation is also used for solving a real type network....
