Hydrogen gases at 3 bar and 1 bar are separated by a plastic membrane having thickness 0.25 mm. the binary diffusion coefficient of hydrogen in the plastic is 9.1 x 10-3 m2/s.
The solubility of hydrogen in the membrane is 2.1 x10-3 kg-mole/m-3 bar An uniform temperature condition of 20oC is assumed.
Calculate the following
1. Molar concentration of hydrogen on both sides
2. Molar flux of hydrogen
3. Mass flux of hydrogen
