浅析计算机在城市给水系统中的应用（Analysis of the application of computer in urban water supply system） Analysis of the application of computer in urban water supply system Abstract: the water supply pipe network system is a pipeline, pump, valve (valve, valve, check valve) delivery system and other facilities consisting of water, through reasonable system design and operation management, can save a lot of project investment, improve the economic efficiency of enterprises and the modernization level of science and technology. Network investment is large, there are many factors at the same time involved, how to determine the optimal design parameters of the system, so that in the premise of meeting the user requirements, to achieve the investment and operation cost the province; how in some systems with known parameters, analysis on the operation of the system, in order to optimize the dispatching automation control etc. and these are the practical problems of water supply pipe network design and management personnel urgent. Key words: water supply; computer; software Urban water supply network system is one of the important systems to ensure industrial production and mass life. Using computer and its application software to solve the problem of optimal operation of pipe network, improve management efficiency and save operating cost, is the basic direction of development of new theory and new technology of water supply system. The calculation model of urban water supply network is established by using object oriented visual programming technology. According to the structural parameters of the pipe network (pipe network figure, diameter and length of pipe section, resistance coefficient, node flow, etc.), the flow rate and water head loss of each pipe section are calculated. On this basis, can also get the node hydraulic pressure and water supply pressure and other parameters, so as to fully understand the working conditions of the network, and the network optimization, reconstruction
