Sugarcane is produced by dissolving the sugar in the sugarcane in water, filtering the solution, heating the solution in a vacuum, cooling the solution to crystallize the excess solute, and filtering. If 90% of all the sugar in the sugarcane is able to be extracted by the water, determine the amount of Recycle from the 2nd filter to the inlet of the vacuum evaporator. The sugarcane and water enter at a ratio of 1:3.
