A reverse osmosis membrane has a water permeation coefficient of 2 x 10-5 cm3/(cm2-sec-atm). It is used to treat a brackish water stream at 25 0C that contains 5,000 mg/L of salt (NaCl).

Question 1: Compute the osmotic pressure of the brackish feed stream

Question 2 – If the feed pressure is 27.2 Atm and the membrane area is 5 m2, what is the permeate flow rate.

A dilute salt water solution has an osmotic pressure of 5 atm at 15 degrees C. Calculate the difference between the chemical potential of the water in the solution and that of pure water. Assume that the density of the solution is the same as that of pure water. The volume of the solution is 1 liter. The density of water is 1 g/cm3. Hint: since the solution is dilute, we can approximate by saying the volume of the solution...
