a) A cellulose acetate membrane is used at 25°C for desalination of seawater containing 4000 ppm total salts. Determine the hydrostatic pressure required in the system in order to have 500 ppm permeate solution. (The solvent permeability constant is 4* 104 kg/sm atm and solute permeability constant is 5.4x 10-7m/s; (g)250c= 999kg/m²) (Assume that the concentration of permeate is very low, if necessary) (15p) NOTE: The osmotic pressure of seawater is given by the following equation; Osmotic press (atm) = 3* [C] +0.5; [C]=concentration of total salts in seawater (g/L)
