A flat 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.

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
