I can't seem to get the selectivity that you have in the hints. Isn't selectivity = (wt%2/wt%1)p / (wt%2/wt%1)f where 2 is water, 1 is ethanol, p is permeate and f is feed? My answer is a degree of magnitude lower.
karen:
I apologize. I just calculated selectivity as the ratio of the permeance for the 2 species.
