Abstract | The previous work on distribution system design or analysis has concentrated on solving the unknown hydraulic pressure at node and flow rate in the pipe . The Hardy Cross method was one of widely used in design or analysis of the hydraulic network. This method although could have an economical solution but might not necessarily be the optimum one. The problem solved by L.P. reaches the optimal because the approach is based on t he principle of mathematics. Although the economical design could be solved for a certain network, but the optimal distribution in the pipeline of the network has not yet been round. The different flow distribution in the network gives the different design and cost; thus different approaches were used in this study . No simple way is possible to find the optimal flow distribution by an exact method, so the heuristic method was used which is a percentage of nodal flow distribution (10/90 and 70/30 only ) a nd minimal flow in linking pipe and computed node pressure difference flow at a connected pipe, respectively. The shortest path (SP ) and minimal spanning tree (MST) for a network is logical and reasonable. Based on these concepts with the f our design procedures t he result gives the SP design of 70/30 nodal flow distribution which could be used. |
