Fick's second law formula
WebFick's law describes the movement of particles over time. There are a few strategies for maximizing particle movement, such as minimizing the distance the particles have to … WebThe Fick's Law (one dimensional diffusion with time) calculator computes the concentration along the x-axis after some period, t. INSTRUCTIONS: Choose units and enter the following: (n0) Concentration maintained at the boundary. (D) Diffusion Coefficient (units: m 2 /s ) (x) Distance in x-direction. (t) Time.

Webto combine Fick’s rst law with the general equation of mass conservation, namely @ tC+ rJ D= 0 (2) where ris the divergence operator. In the case where Dis a constant, this leads to @ tC= D C (3) which is usually referred to as Fick’s second law. This is the equation that has to be solved if you want to calculate a concentration pro le.
