The purification of hydrogen gas is possible by diffusion through a thin palladium sheet. Calculate the number of kilograms of hydrogen that pass per hour through a 8.6-mm-thick sheet of palladium having an area of 0.18 m? at 500°C. Assume a diffusion coefficient of 2.2 × 10°8 m²/s, that the concentrations at the high- and low-pressure sides of the plates are 2.1 and 0.41 kg/m³ of hydrogen per cubic meter of palladium, and that steady-state conditions have been attained.

Transcribed Image Text:The purification of hydrogen gas is possible by diffusion through a thin palladium sheet. Calculate the number of kilograms of
hydrogen that pass per hour through a 8.6-mm-thick sheet of palladium having an area of 0.18 m2 at 500°C. Assume a diffusion
coefficient of 2.2 × 108 m2/s, that the concentrations at the high- and low-pressure sides of the plates are 2.1 and 0.41 kg/m3 of
hydrogen per cubic meter of palladium, and that steady-state conditions have been attained.
