【摘要】 本文对环状管网运行中仅开启一个出水口的水力计算方法进行了探讨。计算出了特征长度系数、平均特征长度系数和最大特征长度系数,并将其排成数表供直接查用。同时计算出了双环管网平均和最大特征长度系数的回归方程,经比较,本文提出的计算方法简单、可靠,便于设计中应用。更多还原

【Abstract】 Hydraulic calculation methods for circular networks performing with one outlet opened have been studied in this Paper. Specific length coefficient and mean specjfic length coefficient as well as maximum specific length coefficient have been calculated and arranged into tables respeetively. The tables may be used directly. Regression equations of the mean and maximum speeific length coefficients of double-ciycular-network have been obtained also. The calculation methods are simple, reliable and convenient for designer.更多还原
