Multicomponent isothermal diffusion and forced flow of gases in capillaries

Abstract Isothermal transport is described of a multicomponent gas mixture in a capillary. The governing equation (eqn 24) derived in the paper accounts for sim and pressure. The equation applies to the transition region between the Knudsen diffusion and the region of continuum and provides also for the slip on equations for the H 2 C 2 H 2 , H 2 C 2 H 2 C 2 H 4 and H 2 N 2 NH 3 mixtures indicates give rise to a pressure gradient representing the driving force for additional transport.
