Problem 2. A reverse osmosis membrane has a kw values of 2.5-10 L/(m²-s-bar) and an average ks value of 3.5.10+ L/(m²-s). Find the expected permeate salt concentration of chloride if the feed concentration is 4500 mg/L, the system operates at a gauge pressure of 35 bar on the feed side of the membrane, and 95%. Assume the permeate has a negligible osmotic pressure. Answer: 171 mg/L.
