以一段带三通的并联风管为例 ,分析了根据该压力平衡公式调整管径时存在的问题及其原因。建议对调整后的管径进行验算 ,以减少误差。 Taking a section of parallel duct with tee as an example, the problems existing in adjusting the diameter according to the pressure balance formula and the reasons are analyzed. It is recommended to check the adjusted diameter to reduce the error.
