A thin-walled vessel containing 2 liter of CO2 gas is kept at a temperature of 10°C. The gas slowly leaks out through a circular hole of diameter 100 um. The outside pressure is vacuumed that leakage back into the vessel is negligible. The diameter of CO2 molecule is about 4.6x10-10 m and its molecular weight is 44 kg/kmol. Estimate the time for the pressure to drop to one-half its initial value.
