这里所说的湿空气是指含有水蒸汽的空气。湿空气的容重(或称为湿空气的重率)是指1立方米湿空气的重量(公斤)数,常用γ(公斤/立方米)表示之。随着矿井逐步向深部开发,以及湿空气同其周围介质的一系列热湿交换作用,使γ值也产生了变化。在正常通风管理中,例如对根据不可压缩稳定流推导出来的伯努利方程式的应用,风量
Wet air here refers to the air containing water vapor. Wet bulk density (or wet air weight) refers to the weight of 1 cubic meter of wet air (kg), commonly used γ (kg / cubic meter) said. With the gradual development of deep wells and humid air and the surrounding medium with a series of heat and humidity exchange, so that the value of γ has also changed. In normal ventilation management, such as the application of Bernoulli’s equations derived from incompressible and steady flow, the volume of air
