Abstract The water supply project is one of the important projects in our orld, that is required for developing . The water distribution system eluding, pipes, fittings, valves, tanks and pumps. Determining the osts of project, and how to minimize these costs are the most important bjectives through analysis and design with good level of service. The cost of the distribution system of any water supply system may account or 50% or more for the system entire cost. Water network of any city requires periodic expansion and improvement to get rid of bad service problems. Taking into consideration a flow distributions which satisfying the flow continuity at each junction, and conservation of head pressures around any closed loop. Faqus network sector as an example. Several attempts have been carried out and finally a trail was submitted toward solving such problems. Developing optimum solutions are carried out using computer. This thesis studying the factors which affect on the optimum design. These factors are: pressure head, flow rate, pipe diameters, velocity of flow through network pipes and head losses. This study presents the assumed data as population, water consumption and water ource are expected to be in the year 2025, also the inflow, out flow, pressure, pipeline data and junction data. The obtained results of computer are discussed for the two proposed designs which solve most of the drawbacks of the network . The first design is composed of forty three pipes in twelve closed loops and the second design of forty nine pipes in seventeen closed loops. The first design is recommended due to |
