【摘要】 根据多水源环状管网供水系统的组成及布置,本文提出水头平衡法作为解环方程组的基础,得到不同组成的环平差流量计算关系,用以求解各水源的供水量、各管段的流量及各节点的水头值。用FORTRAN77算法语言编制了计算程序。算例计算表明,使用方便,可对多水源环状管网供水系统进行多种工况计算,并能得到满意的结果。更多还原

【Abstract】 This paper advances Balancing Head Method as a basis for solving problems of complicated network which may involve pumping stations (booster stations), reservoirs (sump wells), water towers (elevated impoundments) and pipelines. Discharges of pipelines, heads of junctions can be evaluated efficiently.Computer program with FORTRAN -77 has been worked out. and calculated results of examples are satisfactory.更多还原
