室内消火栓栓口压力计算中存在的疑问

Questions in the calculation of indoor hydrant exit water pressure

依据高等院校的专业教材提供的相关公式计算消防水枪充实水柱所对应的压力和流量值时,发现计算结果与相关的设计手册、措施中的数据不一致。经过比对分析后找出疑似问题所在,同时指出传统计算过程中未考虑水枪自身的局部水头损失,并提出补充完善的建议。

The calculation results are not consistent with the data in the related design manuals and technical measures according to the relevant formulas provided by the professional teaching materials of universities.After comparison and analysis,the problem is found out.And it points out the local head loss of the fire water gun does not seem to be considered in the traditional calculation process.The paper put forward the suggestion of supplement and perfection.
