通风管路末段百米漏风率与有关的风量计算

Calculation Air Leakage Ratio Within the Last 100m Ventilation Pipe and Related Air Volume

本文针对现有通风管路漏风理论存在的问题,提出了通风管路漏风新的评价指标;并通过分析研究,推导出末段百米漏风率的测定方法,及其计算漏风量和风机供风量的公式。

Regarding the problems existed in present theory of air leakage of ventilation pipe, this paper puts forward a new index to evaluate the air leakage of the pipe line. On the basis of analyses and researches, this paper derives a method to measure the air leakage ratio within the last 100m ventilation pipe and the air volume to be provided by the ventilation fans.
