本文所介绍的电算程序可用于圆形或矩形变截面均匀送风管道的计算。由于采用静压复得法原理,文章对计算过程中出现的管道截面扩大问题加以讨论,并提出了使管道截面不扩大的最大孔口数和最大孔口间距的近似计算公式。
The computer program described in this paper can be used for the calculation of circular or rectangular uniform cross-section air supply duct. Due to the principle of static pressure recovery, the paper discusses the problem of pipe cross-section enlargement in the process of calculation, and puts forward an approximate formula for calculating the maximum orifice opening and the maximum orifice opening without increasing the pipe cross-section.
