Helium and air are contained in a conduit 7 mm in diameter and 0.08 m long at 44 deg C and 1 atm. The partial pressure of helium at one end of the tube is 0.075 atm and at the other end is 0.03 atm. Calculate the following for steady state equimolar counter diffusion. (a) Molar flux of He, (b) Molar flux of air, and (c) Partial pressure of helium at half way point of the conduit. Assume the following: D of air(44 deg C) = 0.765 x 10-4 m2/s and 101.32 kpa. R=8314 J/Ka.K
