A type 1-1 shell-tube condenser condenses 5000 kg/h of saturated ethanol vapor at normal pressure with cooling water at 25°C. Liquid ethanol exits the apparatus at a temperature of 600°C. The water leaving the device has a temperature of 400C. Let the heat coefficient of steam side is 6000W/m2.K, liquid ethanol side is 3000W/m2K, water side is 2000W/m2K. Let’s: a) Draw device diagram, line symbol b) Calculate the heat transfer coefficient of the device. c) Calculate the amount of water needed to cool down d) Calculate the number of pipes 21x2mm if L= 50 is selected.
