Part A: In a distillation column set up, one end of a manometer is connected to the reboiler and the other end to the condenser. The manometer fluid is water at 20oC. The condenser is vented to atmosphere. The height of water column connected to the reboiler and condenser are 10 cm and 25 cm respectively from a datum line. What is the gauge pressure in atmosphere at the reboiler? Part B. A distillation column having five stages is operating at total reflux conditions. The reboiler contains a solution of sodium chloride in water and the reboiler temperature is 106oC. The condenser is vented to atmosphere and you may assume pressure drop across the column is negligible. Predict and justify the temperature readings in stages one through five of the column
