WebFick s second law defines the behavior of a diffusing chemical in space over time. Fick s second law is derived from Fick s first law and the equation of continuity for a solute. For simplicity, we derive Fick s second law in 1-D coordinates. This can readily be extended to multiple dimensions or to spherical coordinates [22]. [Pg.18] WebSo, Fick’s first law can be considered as a specific (simplified) format of the second law when applied to a steady state. Now, let’s consider two real practical cases, and see how to solve the Fick’s second law in these specific cases. …
