Question:
Difusion of CO2 Through Rubber. A flat plug 30 mm thick having an area of 4.0 x 104 m2 and made of vulcanized rubber is used for closing an opening in a container. The gas CO2 at 25°C and 2.0 atm pressure is inside the container. Calculate the total leakage or diffusion of CO2 through the plug to the outside in kg mol CO2/s at steady state. Assume that the partial pressure of Co2 outside is zero. From Barrer (B5) the solubility of the Co2 gas is 0.90 m gas (at STP of 0°C and 1 atm) per m3 rubber per atm pressure of CO2. The diffusivity is 0.11 x 10-7m2/s.
