The molar flux through a unit area of the material is proportional to the concentration gradient. Flux is directly proportional to gradient. Fick’s law describes diffusion from spheres along the concentration gradient as:(10.1)∂c∂t=d∂2c∂r2+2∂cr∂rwhere c is cmm concentration in coal in ft3/ft3, t is time in second, d is coefficient of diffusion in ft2/s, and r is radial coordinate in ft.
