The purification of hydrogen gas by diffusion through a palladium sheet. Compute the number of kilograms of hydrogen that pass p
er hour through a 5-mm-thick sheet of palladium having an area of 0.20 m2 at 500°C. Assume a diffusion coefficient of 1.0 × 10-8 m2/s and that the concentrations at the high and low pressure sides of the plate are 2.4 and 0.6 kg of hydrogen per m3 of palladium. Assume steady state conditions.
<em>The mass of the hydrogen for one hour would be 0.0039168 kg/hr</em>
Explanation:
The concentration and the distance at concentration point is calculated before calculating the mass of hydrogen. The attached images show a clear explanation;
Work done by a system is not a property because it doesn't define the system's state. Work is mechanical energy exchanged across the system's boundaries.
