Question 3: a 3, A reverse-osmosis membrane to be used at 25C for a NaCl feed solution containing 2.5g NaCl/L (2.5kg NaCl/m?p=999kg/m?) has a water permeability constant Aw = 4.81x10^kg/s.m.atm and a solute (NaCl) permeability constant As = 4.42x10-?m/s. the membrane is concentration polarized such that B=1.5. Calculate the water flux and solute flux through the membrane using AP = 27.2 atm and the solute rejection, R. Also calculate c2 of the product solution
