2. Concentrated orange juice is produced using two consecutive evaporators. A fresh feed containing 75 mass \% water and orange juice enters the process at a rate of 300kg/hr where 110kg/hr of pure water is remove at the first evaporation stage and 90kg/hr of pure water is evaporated at the second stage. In order to get the required 25 mass % water in the final product, 10kg/hr of the fresh feed bypass the two evaporation stages to be mixed with the process stream exiting the second evaporation stage. The final product is to contain 25 mass % of water. a. Draw and completely label a schematic diagram of the process. (10 marks) b. Calculate all unknown streams flow rates and compositions (mass fractions of components in each streams). (20 marks)
