分析目前常用的自动喷水灭火系统特性系数水力计算法所存在的缺陷,在理论推导配水支管起端水压与末端喷头出流量关系的基础上,提出了支管特性系数水力计算法,并介绍了利用EXCEL软件简化计算的方法。
Based on the analysis of the shortcomings of the hydraulic coefficient calculation method of the characteristic coefficient of the sprinkler system commonly used at present, this paper proposes the hydraulic calculation method of the branch pipe characteristic coefficient based on the theoretical derivation of the relationship between the water pressure at the beginning of the branch pipe and the discharge of the terminal nozzle. Using Excel software to simplify the calculation method.
