Diffusion coefficient is the proportionality factor D in Fick's law (see Diffusion) by which the mass of a substance dM diffusing in time dt through the ...

Diffusion Coefficient

Diffusion constant: D = 2.9 × 10−5 cm2 s−1 = 2900 μ2 s−1. Temperature: T = 310.15 K. Surface tension: γ = 70 dyne cm−1 = 0.7 μatm.

Diffusion Coefficient Definition

2015年1月14日 — From the above definition, the diffusion coefficient has units of area per time (m2 s-1, or m2/s in SI units). These units are also clear from a ...

Fick's laws of diffusion

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 ...
