The fluid velocity at the microscopic level varies in magnitude and direction from point to point within a fluid present in the void space.As a consequence, any initial cloud of close tracer particles will spread out, gradually changing its shape and the fluid volume occupied by it.he components of are related to the property of the porous medium to disperse a component, to the velocity of the fluid, and to molecular diffusion, by.
