Following is the data of carbon dioxide in polymer polypropylene (PP) Diffusivity =9.6x10 -9m 2 /s Solubility = 0.75 x 10 -8 [g-gas/(g-PP).atm] Density of polypropylene = 0.78 g-PP/cm 3PP CO2 is diffusing through a flat sheet of thickness 3 mm made of PP Partial pressure of CO2on one side = 0.29 atm Partial pressure of CO2on the other side = 0.5 atm I. Compute the concentrations on both sides (CA1 and CA2 ) in the solid polymer PP in ggas/cm 3 -PP II. Determine flux of diffusion in g-gas/cm 2 .s
