Steady State Diffusion Problem 6.8 The purification of hydrogen gas by diffusion through a palladium sheet was discussed in Section 6.3. Compute the number of kilograms of hydrogen that pass per hour 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 high- and low-pressure sides of the plate are 2.0 and 0.4kg of hydrogen per cubic meter of palladium, and that steadystate conditions have been attained
