气体压缩系数,也称压缩因子Compressibilityfactor。是实际气体性质与理想气体性质偏差的修正值。通常用Z表示,;Z也可以认为是实际气体比容v(vactual)对理想气体比容videal的比值;Z=vactual/videal;videal=RT/P。
气体在标况下的压缩系数;
从本质上分析了理想气体状态方程的局限性,提出了利用压缩系数提高天然气流量精度的概念,从而改进了状态方程。
Analying the limit of state equation of ideal gas in substance, the conception that using compressional factor improves the accuracy of gas flux is introduced and the state equation is mended.
And you can find these compressibility factors in tables. If you want to know the compressibility factors for water, for steam, at a certain pressure and temperature, you go to a table and you find it.
各种气体的压缩系数,想知道水或者水蒸气,在某个温度和压强下的,压缩系数,查表就行了,这是实际气体状态方程的。
