The purification of hydrogen gas by diffusion through a palladium sheet was discussed in section 5.3. compute the number of kilo- grams of hydrogen that pass per hour through a 6-mm-thick sheet of palladium having an area of 0.25 m2 at 600oc. assume a diffusion coefficient of 1.7x10^-8 m2/s, that the con- centrations at the high- and low-pressure sides of the plate are 2.0 and 0.4 kg of hy- drogen per cubic meter of palladium, and that steady-state conditions have been attained
