末段终点流量增大时,末段起、终点压力都要减小。相反,终点流量减小时,末段起、终点压力都要增大。When the terminal flow increases, the terminal pressure should be reduced. On the contrary, when the terminal flow decreases, the terminal pressure increases.
在最优末段长度的条件下,末段终点的最高压力等于起点的最低压力。It can be seen that: under the condition of the optimal terminal length, the maximum pressure at the terminal point is equal to the minimum pressure at the starting point.

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
