## Fick's first law

Fick's first law states that the diffusive flux goes from regions of high concentration to regions of low concentration, with a magnitude that is proportional to the concentration gradient and the proportionality constant is the diffusion coefficient.

## How to Calculate Diffusion Flux?

Diffusion Flux calculator uses Diffusion flux=Diffusion coefficient*(Concentration difference/Distance) to calculate the Diffusion flux, Diffusion Flux is the mass diffusing through and perpendicular to a unit cross-sectional area of solid per unit of time. Diffusion flux and is denoted by J symbol.

Here is how the Diffusion Flux calculation can be explained with given input values -> 1.500E-9 = 3E-11*(0.5/0.01).

### FAQ

What is Diffusion Flux?
Diffusion Flux is the mass diffusing through and perpendicular to a unit cross-sectional area of solid per unit of time and is represented as J=D*(ΔC/d) or Diffusion flux=Diffusion coefficient*(Concentration difference/Distance). Diffusion coefficient is the proportionality factor D in Fick's law , Concentration difference is the difference in concentration of diffusing species and Distance (length) across which the diffusion is taking place.
How to calculate Diffusion Flux?
