Problem III. (7 Points) A 5mm thick porous solid divider separating a reservoir of water into two sides. In the left side the water is contaminated with CO2 (at a concentration 0.2kg mol/m3 ) whereas the right side contains pure water. If mass transfer is taking place at 25C under steady state conditions and faces no resistance but that in the water filled porous solid divider, calculate the flux of CO2 into the right side in kgmol/sm2. The solid divider is made of vulcanized rubber with a void fraction of 0.4 and a tortuosity of 3. Assume concentration of CO2 in both sides is constant
