Simple expressions for the diffusion and flow of binary gas mixtures through small capillaries are given. These expressions constitute a modification of Mason's formulae and include especially the effects of collision cross sections. A generalized Bosanquet-equation is also obtained.
Ibis paper presents the results of an anaIysis of dispersion in a porous medium, for the case when Dorcy's law is valid and the P&let number is large. It is shown tbat, after a sufficiently long time, the effective longitudinal diffusivity is a logarithmic function of the Pellet number. RBsume-Analy
