During the distillation process, the input flow rate is 1000 mol/h containing 30% ethanol, 40% water, and 30% ethylene glycol. There are three output streams: 1st output stream contains 70% ethanol and 30% water; 2nd output stream contains 20% ethanol and 40% water; 3rd output stream contains 5% ethanol and 50% water. Solve the material balance using both MatLab and Python and calculate the flow rates for all three output streams. a) Draw and label the PFD from the information given above, highlighting all the unknown variables. (You should define each variable first, e.g. n; represents ....) b) Perform a degree-of-freedom analysis.
