Consider a sheet of Iron which is maintained in an atmosphere filled with nitrogen and is permitted to achieve and steady state diffuseion. The thickness of the sheet is 6.5mm. The diffusion coefficient of nitrogen in iron is 1.9 × 10-11 m2/s at 6750C. If the concentration on the high-pressure side of the plate is 3kg/m3 and the diffusion flux is 1.7 × 10-8 kg/m2 s . Determine the concentration on the low-pressure side of the plate if the depth of concentration of low-pressure side is 0.001 m.
