A cellulose acetate membrane is used at 25C for desalination of seawater containing 4000ppm total scelits. Determine the hydrostatic pressure (P) required in the system in order to have a rejection value (R) of 0.98 . The solvent prermeability constant is 4.104kg/s.m2.atm and solite permeability constant is 5.4107m/s.
