A large tank filled with a mixture of gases A and B at 101 kPa and 298 K (25 °C) is connected to another large tank filled with a mixture of A and B of different compositions of A and B at 101 kPa and 298 K (25 °C). The tanks are connected by a tube of inner diameter of 50 mm and is 150 mm long. Calculate the steady state rate of transport of A through the tube when the concentration of A in one tank is 90 mole % and in the other is 5 mole % assuming uniformity in the composition in each tank and transfer takes by molecular diffusion. The diffusivity of A in B is 4.3 x 10-³ m²/s.
