Modification of Calculating Program for Water Supply Pipe Network

Not being satisfactory at function, the present calculating program for water supply pipe network is modified in this paper.The new program,which selects independent meshes automatically,is more convenient to input original data,thus it is suitable to designing different structures of pipe networks and to running management of more than one water source,and it is capable of outputing pipe quantity,node pressure,water tower height or water pump working state and so on.In one word,the new program is more convenient and more effective than many other ones nowaday.Simple examples are used to explain its function.
