Extracted text: A distillation column is a process unit in which a feed mixture is separated by multiple partial vaporizations and condensations to form two or more product streams. The overhead product is rich in the most volatile components of the feed mixture (the ones that vaporize most readily), and the bottom product stream is rich in the least volatile components. The following flowchart shows a distillation column with two feed streams and three product streams: m m3(kg A/h) n m(kg/h) 0.03 kg B/kg 0.97 kg C/kg 1200 kg/h 0.70 kg A/kg y4(kg B/kg) zg(kg C/kg) f 5300 kg/h x2(kg A/kg) y2(kg B/kg) mg(kg/h) 0.60 kg B/kg 0.40 kg C/kg a. Complete the above degree of freedom analysis Number of unknowns which must be specified b. Suppose values are given for mjand x2. Give a series of equations, each involving only a single unknown, for the remaining variables. Circle the variable for which you would solve. (Once a variable has been calculated in one of these equations, it may appear in subsequent equations without being counted as an unknown.)
