Could you solve a and b?

Question 2 (20 pts). Two feed streams are fed into a distillation column at steady state. First feed stream consisting of 30% by mass of A and balance B has mass flow rate of 7400kg/h. Second feed stream consists of 3%B by mass and balance of C. Three product streams are withdrawn from the column continuously. First product stream consists of pure A, second product stream has a flow rate of 2300kg/h with 70%A and 15%B by mass and balance C, third product stream consists of 60%B and balance C. a) Draw the flowchart of the process and perform degrees of freedom analyses. b) Calculate all the unknown flowrates of the feed and product streams for the process
