They can be used to solve for the diffusion coefficient, D. Fick's first law can be used to derive his second law which in turn is identical to the diffusion equation. A diffusion process that obeys Fick's laws is called normal or Fickian diffusion; … See more In 1855, physiologist Adolf Fick first reported his now well-known laws governing the transport of mass through diffusive means. Fick's work was inspired by the earlier experiments of Thomas Graham, … See more Fick's first law relates the diffusive flux to the gradient of the concentration. It postulates that the flux goes from regions of high … See more Fick's second law is a special case of the convection–diffusion equation in which there is no advective flux and no net volumetric source. … See more • Advection • Churchill–Bernstein equation • Diffusion See more Fick's second law predicts how diffusion causes the concentration to change with respect to time. It is a partial differential equation which in one dimension reads: $${\displaystyle {\frac {\partial \varphi }{\partial t}}=D\,{\frac {\partial ^{2}\varphi }{\partial x^{2}}}}$$ See more Equations based on Fick's law have been commonly used to model transport processes in foods, neurons, biopolymers, pharmaceuticals See more • Berg HC (1977).
