矿井注氮气防灭火管路阻力计算

The nitrogen injection mine fire prevention resistance calculation

对氮气流动的基本参数、流动状态进行了定性、定量的说明,对管路的直管阻力及总的阻力计算进行了理论推导,得出氮气流动阻力的计算公式。

It has carried the flow state of the qualitative and quantitative description and had a theoretical calculation of the resistance of the pipe, derived nitrogen flow resistance calculations formula.
