9 evaporators are connected in series, i.e., the concentrated product of the first one is fed to the second one, and so on. The solvent vapor generated is equal in all evaporators. Let's consider this set-up being used on the concentration of a salt. If the feed to the first evaporator is 466.0 kg/h with 1.07% salt and the product of the last evaporator contains 6.49% salt, determine the salt concentration on the product of the 4th evaporator.
