气体的粘度随压力增高而增高。在低压时,气体粘度随温度升高而增加,随着压力的增加,温度升高对粘度增大的影响越来越小,当压力很高时(100×105Pa以上),气体粘度随温度升高而降低,明显表现出类似于液体的性质。Table 1-13 shows the dynamic viscosity of methane at different pressures and temperatures. It can be seen from the table that the viscosity of gas increases with the increase of pressure. At low pressure, the gas viscosity increases with the increase of temperature. With the increase of pressure, the influence of temperature increase on the inc
