13 Facts About Fick's law

Fick's first law can be used to derive his second law which in turn is identical to the diffusion equation.

Fick's law is analogous to the relationships discovered at the same epoch by other eminent scientists: Darcy's law, Ohm's law, and Fourier's Law .

Fick's law experiments dealt with measuring the concentrations and fluxes of salt, diffusing between two reservoirs through tubes of water.

Fick's first law relates the diffusive flux to the gradient of the concentration.

In one dimension, the Fick's law can be written in various forms, where the most common form is in a molar basis:.

Fick's second law predicts how diffusion causes the concentration to change with respect to time.

Fick's second law has the same mathematical form as the Heat equation and its fundamental solution is the same as the Heat kernel, except switching thermal conductivity with diffusion coefficient :.

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.

Equations based on Fick's law have been commonly used to model transport processes in foods, neurons, biopolymers, pharmaceuticals, porous soils, population dynamics, nuclear materials, plasma physics, and semiconductor doping processes.

One more general framework is the Maxwell–Stefan diffusion equationsof multi-component mass transfer, from which Fick's law can be obtained as a limiting case, when the mixture is extremely dilute and every chemical species is interacting only with the bulk mixture and not with other species.

Fick's law can be used to control and predict the diffusion by knowing how much the concentration of the dopants or chemicals move per meter and second through mathematics.

In many realistic situations, the simple Fick's law is not an adequate formulation for the semiconductor problem.

Fick's first law can be used to predict the changing moisture profiles across a spaghetti noodle as it hydrates during cooking.
