EMD in a Tube.
Two bulbs are connected by a straight tube, 0.001 m in diameter and 0.15 m in length. Initially the bulb at End 1 contains N2 and the bulb at End 2 contains H2. Pressure and temperature are constant at 25oC and 1 atm. At a time after diffusion starts, the nitrogen content of the gas at End 1 of the tube is 80 mol% and at End 2 is 25 mol%. If the
binary diffusion coefficient is 0.784 cm2/s, determine:
(a) The rates and directions of
(b) The species velocities relative to stationary coordinates, in cm/s.
