Problem 3. (30 Points) You are testing gas permeation through a bilayer film consisting of a polyethylene layer (1) and a nylon layer (II). You don't know the thickness of either layer (Lor L.), but you know the following permeabilities: PMU, O2 = 0.029 x 102 m O2(STP) msolid-atm m 02(STP) Oxygen permeabilities: Pio2 = 4.17 x10 12 msolid atm m N2(STP) msolid atm Nitrogen permeabilities: Pin2 = 1.52 x 1012 mosolid atm PUN2 = 0.0152 x 10-12 m N3(STP) You measure the flux of nitrogen and oxygen through the bilayer film using a pressure drop of 6.5 atm: Nitrogen: Na = 1.60 x 100 kgmol/sm? Oxygen: NA = 3.17 x 10 kgmol/sm? What is the thickness of the nylon layer (L.) in mm
