1. In the concentration of orange juice 1000kg/h of fresh extracted and strained juice containing 7.00% by mass solids is fed to a vacuum evaporator. In the evaporator, water is removed and the solids content increased to 58.0% by mass. (hint: treat the non-volatile "solids" as a species.) a) Draw and label the flow chart for this process. Use variable notation to label the amount and composition of each flow stream. b) Perform a degrees of freedom analysis based on your flowchart. Explicitly state the unknown variables, material balances and other independent equations. c) Calculate the mass flow rates and compositions of the outlet steams of concentrated juice and water
