The solution of kinetic equation for the quantum and classical gases with
diffusion boundary conditions has been obtained for an arbitrary capillary
width d-to-mean free path l ratio. This solution allowed us to obtain
analytical expressions describing both the stationary states of the gas
filling in two containers connected by a capillary and the thermal slippage
effect. The relations obtained have made it possible to observe the
transition from the Knudsen regime (d<< l) to the hydrodynamic one
(d>> l).
This results take into account the influence of statistics and geometry
of the capillary as well.
