Pressure distribution in a circular tube under a free molecule regime was analyzed by utilizing local Maxwellian and Monte Carlo methods.
It is recognized that pressure slip at the entrance and exit of the tube exist and the distribution is linearly changed along the tube axis.
The magnitudes of the slips increase with the decrease of the ratio of length to radius of tube and the ratio of pressure at the exit to that at the entrance.
