2) Compute the number of kilograms of hydrogen that pass per minute through a 6-mm thick sheet of palladium having an area of 0.25m2 at 600C. Assume a diffusion coefficient of 1.7108m2/s, that the respective concentrations at the highand low-pressure sides of the palladium plate are 2.0 and 0.4 kg of hydrogen per cubic meter, steady-state conditions have been attained. ( 5 points) 3) Nitrogen from a gaseous phase is to be diffused into pure iron at 700C. If the surface concentration is maintained at 0.1 wt%N, what will be the concentration 1mm from the surface after 10h ? The diffusion coefficient for nitrogen in iron at 700C is 2.51011m2/s.
