A membrane separation process is used to separate a 5 wt% salt solution into a retentate stream and a permeate stream. The membrane has a rejection coefficient of 0.95 for the salt, and a flux of 2 L/m^2.hr when operated at a transmembrane pressure of 5 bar. The feed solution is fed to the membrane at a flow rate of 10 L/min, and the retentate is withdrawn at a flow rate of 7 L/min. What is the flow rate of the permeate stream, and what is the concentration of the salt in the permeate stream?
