未知题型 在输气干线中压力高达几个甚至几十个兆帕(106Pa)时,天然气与理想气体之间的性质差别较大,在工程上用压缩因子Z来表示真实气体与理想气体pVT特性的差别。其状态方程写作When the pressure in the gas transmission trunk is up to several or even dozens of mpa (106Pa), the nature of natural gas and ideal gas is quite different. In engineering, the compression factor Z is used to represent the difference between the pVT characteristics of real gas and ideal gas. Its equation of state is written 对1kg气体On 1 kg gas pv=ZRT
