Aflat plug 30 mm thick having an area of 4.0 × 10–4m2 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 (b1), the solubility of the co2 gas is 0.90 m3 gas (at stp of 0°c and 1 atm) per m3 rubber per atm pressure of co2. the diffusivity is 0.11 × 10–9m2/s.
