Fick law equation
WebCombining the above expression with Fick’s first law, J = −D∂c/ ∂x, we obtain the steady state flux through the membrane, (C A CB) h. KD J = −. In the literature, the combination KD/h is called the permeability or sometimes the permeance of the membrane, and the previous equation is then written as. J = P (C A −CB).

WebA familiar equation for Fick's First Law Fick's Law again:Flux is directly proportional to gradient. Now we know that the gradient is represented bydC/dx, but what does “directly Put simply, it means this: small gradient --> small diffusion BIG gradient --> BIG diffusion WebEquation 3.5a is better known as Fick’s second law. One important point, however, should be noted here that it is not possible to use Fick’s first law to estimate the distribution of components over the whole interaction zone in a Fig. 3.3 Change in flux with distance in a very thin slab 118 3 Fick’s Laws of Diffusion
WebFor optical diffusion, Fick's 1st law is expressed as the energy flux J [W cm -2] proportional to the diffusion constant D [cm] and the negative fluence gradient dF/dx: which was obtained by substituting cD for and substituting F/c for C. The factors c and 1/c cancel to yield the above equation.
