A tank initially contains 80% nitrogen and 20% oxygen, while a second tank contains 20% nitrogen and 80% oxygen. The tanks are connected by a 15 cm long and 5 cm inner diameter pipe. The total pressure of the system is 2 atm, and the temperature is maintained at 20C.

a. Calculate the transfer rate of nitrogen gas. b. Determine the partial pressure of nitrogen gas at a point 5 cm away from the first tank.

Note: The experimental diffusivity of nitrogen in oxygen gas at 316 K and 1 atm pressure is found to be 0.23 cm2/s.
