Derivation of fick's first law
WebAccording to Fick's First Law, these quantities are directly proportional to each other (remember the function is like y = mx) and -D is the slope. If you are interested in the diffusion of glucose instead of oxygen, you get a different diffusion coefficient D, and so the line has a different slope. 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. ... And if you go back in your review and think about what the meaning of the second derivative is, it's actually describing what ...

Fick’s first law of diffusion states that the movement of solute takes place from higher concentration to lower concentration. … WebDerivation of Fick's second law. Consider a cylinder of unit cross sectional area. We take two cross-sections, separated by δx, and note that the flux through the 1st section will not be the same as the flux through the second section. From Fick’s first law we can deduce that: J 1 = − D { ∂ C ∂ x } 1 J 2 = − D { ∂ C ∂ x } 2 J 2 ...
