Aliquid mixture containing 35 mass percent of ethanol (e) and 65 mass percent water (w) is fed to a distillation column operating at steady-state. a top product stream contains 90 mass percent e while the bottom product stream contains 5% by mass of e fed to the column while e rest is w. the feed mixture is entering the column at 100 l/h. the specific gravity of the feed is 0.93. [15 pts] try to draw the diagram. this diagram can be found in the supplemental homework sheet. a. how many independent stream variables are there? b. how many known, given pieces of information (i. e. it is not an equation) are provided? c. how many independent material balances can you perform? d. are there any additional relationships (process specifications) provided? e. what are the degrees of freedom? f. if the degrees of freedom is 0, calculate the exit flow rates of both the top and bottom streams. if you cannot solve the problem explain why
