Concentration of many food products (juices, extracts, syrups, etc.) is carried out by reverse osmosis at a pressure of 17 MPa in an apparatus with a cellulose acetate membrane. Calculate the concentration of the resulting solution if the osmotic pressure in it at 20 ° C is equal to: 1.48 MPa for orange juice; 2.45 MPa for coffee extract.
