The characters of compressibility and thermodynamics have some effect on the gas flowing, so the analysis on the flow of gas is more complex than that of liquid. But under different conditions and different requirements of precision the analysis can be simplified suitably, then make the formulae given become simple subsequently. This paper analyzes various gas flux based on basic characters and motion laws of gas and the analysis is just applied in an engineering project.展开更多
