Question

Methane diffuses at steady state through a tube containing helium for the case equimolar counter diffusion. At point 1, the partial pressure of methane is 55 kPa and at point 2, 0.03 m apart is 15 kPa. The total pressure is 101.325 kPa and temperature is 298 k, at this temperature and pressure the value of diffusivity is 6.75 × 10-5 m2 /s. Calculate (a) the steady state flux of methane from point 1 to point 2 (b) the partial pressure of methane at point 0.01 m apart from point 1 for the above case

Answer #1

Ammonia gas (A) is diffusing at steady-state through N2 (B) by
equimolar counter-diffusion in a circular conduit 1.22 m long at 25
degrees celsius and a total pressure of 101.32 kPa absolute. The
partial pressure of ammonia at the left end is 25.33 kPa and 5.066
kPa at the other end. The conduit has a diameter of 0.0305 m at the
left end and tapering uniformly to 0.0610 m at the right end. The
diffusivity is 0.023 x 10–4 m2...

A gas of CH 4 and He is contained in a tube at 101.32 kPa
pressure and 298 K. At one point the partial pressure of methane is
p A1 = 60.79 kPa, and at the point 0.02 m distance away, p A2 =
20.26 kPa. If the total pressure is constant throughout the tube,
calculate the flux of CH 4 (methane) at steady state for equimolar
counterdiffusion
