WebFick’s second law can be derived from Fick’s first law by considering two planes X and Y at positions x and x + d x ⁠, i.e. separated by a small distance dx, in a solid material that has a non-linear concentration profile and, therefore, a varying concentration gradient, as shown in Figure 7.3. The diffusion rates at the two planes are ... fish grill los angeles
