plastic 5. Consider the diffusion of water vapor through a polypropylene (PP) sheet 2 mm thick T pressures of H20 at the two faces are 1 kPa and 9 kPa, which are maintained constant. Th permeability coefficient of H2O through PP is 38 x 103 (cm STP)-cm/cm2-s-Pa. Assumin conditions of steady state, what is the diffusion flux, in [(em STP/em-s), at 298 K? Answer:ー-52,10ーフ (cm3 STP)/cm2-S 1.52 10 5.
