1) Compute the number of kilograms of hydrogen that pass per hour through a 6-mm-thick sheet of palladium having an area of 0.25 m2at 600°C. Assume a diffusion coefficient of 1.7 × 10–8m2/s, and that the concentrations at the high-and low-pressure sides of the plate are 2.0 and 0.4 kg of hydrogen per cubic meter of palladium, and that steady-state conditions have been attained.
