Experimental data has shown that the osmotic pressure, of a solution is proportional to the concentration of the solute and temperature, T. In a routine performance test of a laboratory reverse-osmosis unit, 3750 mg BaCl/L (p= 1000 kg/m) was used to investigate the conditions of the membrane at 25C. The permeability constant Aw was 3.60 x 10-4 kg solvent/s. m. atm and the As was 1.05 x 10-7 m/s. i) Using a AP of 36.5 atm, determine the fluxes, solute rejection, R and product solution concentration.
