摘要
在给水管网计算中,通过建立环-管段矩阵、环-节点矩阵以及输入节点流量、节点坐标等少量数据,通过计算和数据转换,便可求得经济管径、管段设计流量、节点水压值、水厂供水量、管网造价、年费用折算值等。采用该方法进行管网计算,可以减少40%～70%的计算时间。
In calculating feed water network, after establishing the loop pipe segment matrix and loop node matrix and inputing a few data, such as nodal flow and nodal coordinates, economic pipe diameter, pipe segment design flow, nodal water pressure, supplied quantity of water from water plant, network construction cost, conversion value of annual cost, etc., can be obtained through calculation and data conversion. 40%～70% of calculation time can be saved by using this method in the calculation of the network.
