住宅小区给水管道临界当量的计算

CALCULATION OF CRITICAL EQUIVALENT OF WATER PIPES IN RESIDENTIAL AREAS

本文是对“住宅小区给水管道设计流量计算探讨”一文(《给水排水》1991年第3期)中临界流量计算方法的改进,作者提出了影响临界当量的临界特性参数 M,推导出了临界当量计算公式 N_L=A(B^M+C/(M^D))。

This article,being an amendment,of“Discussion on the Design Flow of Water Pipes in Residential Areas”(published in No.a,1991 of the Journal),proposed a critical property parameter M which influences the critical equivalent,and the calcu- lating formula of critical equivalent is derived as follow:N_L=A(B^M+C/M^D).
