WebFick's law is derived based on various assumptions. Therefore, it has certain limitations to apply for various systems. In such cases, suitable modifications are necessary. Let us discuss each of the assumptions one by one. 1) Finite medium Fick's law is derived for an infinite homogeneous medium. WebFick’s law describes the water vapor transfer.

WebLet's examine how Fick's Second Law was developed. First, we're going to look at a volume element, and that volume element is going to be described in terms of the width of the element times the cross sectional area. So we're looking at a region which is a uniform cross section. We're going to be examining the flux that comes into this system ... WebThis derivation has been given in an earlier publication (in the Supporting Information of ref 3).
