WebNov 29, 2024 · Fick’s law of diffusion assumes the mass flux J, with units [ J] = m / t across a cross section of the pipe is given by. (9.1.1) J = − D u x, where the diffusion constant D > 0 has units [ D] = l 2 / t, and we have used the notation u x = ∂ u / ∂ x. The mass flux is opposite in sign to the gradient of concentration so that the flux is ... WebFundamentally, two types of diffusion are distinguished: Tracer diffusionand Self-diffusion, which is a spontaneous mixing of molecules taking place in the absence of concentration (or chemical potential) gradient. This type of diffusion can be followed using isotopic tracers, hence the name.
