用C语言计算自喷系统中的水力问题

摘要

According to the existing not accurate calculation results, low pressure, uneven hydraulic distribution and other defects of recommen-ded area method in Automatic Sprinkler Extingiushment System Design Specification, this paper made the hydraulic calculation procedure into C language computer program, through the two iterative method to calculate the system pressure, and combining with the analysis on example, draw appropriate amplification end water distribution pipe diameter, could effectively reduce the required pressure of pipe network, reduced the uneven of each branch pressure distribution.%针对《自动喷水灭火系统设计规范》中推荐的作用面积法存在计算结果不准确、压力偏低、水力分布不均匀等缺陷，将水力计算过程编成C语言计算机程序，通过二分迭代法计算系统压力，并结合对算例的分析，得出适当放大末端配水干管管径，能有效的减小管网所需压力，减小各支路间压力分布的不均匀性。
