asked Sep 20, 2022 in Mass Transfer by Julian (37.1k points)

For what kind of mixtures DAB=DBA holds?

(a) Ideal

(b) Real

(c) For both real and ideal

(d) This relation is never true.

The question was posed to me in an interview for internship.

Asked question is from Fick’s Law-2 topic in chapter Modes and Diffusion of Mass Transfer

In industries titanium is hardened through diffusion of carbon. The concentration of carbon at 1mm into the surface of the titanium slab is 0.25kg/m^3 and at 3mm the concentration is 0.68kg/m^3. The rate at which the carbon is entering into its surface is 1.27*10-9kg/m^2.s. calculate the value of diffusion coefficient of carbon.

A sheet of Fe 1.0 mm thick is exposed to an oxidizing gas on one side and a deoxidizing gas on the other at 725°C. After reaching steady state, the Fe membrane is exposed to room temperature, and the C concentrations at each side of the membrane are 0.012 and 0.075 wt%. Calculate the diffusion coefficient (m^2/sec) if the diffusion flux is 1.4×10^-8kg/m^2-sec.
