For the following two questions, consider pure helium gas passing through a 1-meter-long plastic pipe. The outer radius of the pipe is 1 cm, and the inner radius is 0.8 cm. The pipe has a temperature of 80°C and is surrounded by air. Chemical analysis of the air surrounding the pipe shows that in a steady state, 1-10-5 mol of helium diffuses through the pipe each second. When the pipe is replaced, a microprobe analysis shows the helium concentration at r = 0.8 cm, cHe = 0.012 mol/cm3, and at r = 1.0 cm, cHe = 0.0002 mol/cm3. Calculate the flux of He through the plastic pipe at the outer surface in units of 10-10 mol/cm2/s Calculate the diffusion coefficient of He in the plastic pipe in units of 10-8 cm2/s.
