The powerful kinetic theory based on a generalized non-equilibrium grand-canonical ensemble was applied to the study of the motion of a fluid when in the presence of space inhomogeneities. The generalized Mori-Heisenberg-Langevin equations provided by the theory were used to derive a generalized Fick's Law. An extended evolution equation for the density of particles was derived, and the conditions when it goes over restricted forms of the type of the telegraphist equation and Fick's diffusion equation were detailed.
