Transcribed Image Text:

A reverse-osmosis membrane to be used at 25C for a NaCl feed solution containing 2.5 g NaCl/L (2.5 kg NaCl/m, p=999 kg/m) has a water permeability constant A = 4.81 x 10 kg/s m atm and a solute (NaCl) permeability constant A, 4.42 x 107 m/s (A1). Calculate the water flux and solute flux through the membrane using a AP-27.20 atm and the solute rejection R. Also calculate c, of the product solution.
