Study On The Impact About Flow Distribution Method To The Reliability And Economic Of The Pipeline Network

The optimal design is a significant task of urban water supply engineering, playing an important role in economic development and improving living standards of people. It has great economic and social benefit to seek the optomal design programme that has the minimum cost, the highest reliability and the maxmum entropy to reduce investment and energy consunption of the water distribution network under the limited project investment.This tractate start from the studying of flow distribution method. the improvement of existing methods basis on the analysising, controlling flow distribution method and reliability allocation methodology at home and abroad. This allocation method to improve traffic law takes into account the tube length, pipe flow uniformity and the impact of factors such as traffic load, has greatly improved the flow of the early hours are reasonable, to make it closer to the optimal value. To a certain town district pipe network design, for example, for different flow distribution program for economic and reliability of the comparison, so as to arrive with a better economy and reliability requirements for traffic allocation.
