A natural gas (methane, CH4) storage facility uses 3-cm-diameter by 6-m-long vent tubes on its storage tanks to keep the pressure in these tanks at atmospheric value. If the diffusion coefficient for methane in air is 0.2 × 10?4 m2/s and the temperature of the tank and environment is 300 K, the rate at which natural gas is lost from a tank through one vent tube is
