本文阐述了影响城市供水压力管道、管径选择的四个因素:水压力、流量、流速及强度。建立了一个城市供水计算经济管径的数学模型,从而减小了工程投资。该模型已经在大禹渡城市供水工程设计中得到运用
This article describes the four factors affecting the selection of pipe and pipe diameter for urban water supply: water pressure, flow rate, flow rate and strength. A mathematical model for calculating the economic diameter of urban water supply was established, thereby reducing the investment in the project. This model has been used in the design of Dadudu City Water Supply Project
