A solution containing 10% NaOH by weight is in a single effect evaporator with a flow rate of 5000 kg/hr. is concentrated. Atmospheric pressure at the evaporation site is 100.5kPa. supply current to the system It enters at 355K. The solution showing a boiling point rise (KNY) of 55 K was in the evaporator at 403 K. is boiling. The saturated steam used as the heating medium is at a gauge pressure of 516.8 kPa. Heating of condensate The temperature to leave the cabin is 368 K. The entire heat transfer coefficient of the system is 2558 W/m2 .K and superheated solvent vapor its specific heat is given as 1.926 kJ/kg.K. a. Calculate the amount of concentrated solution and solvent vapor. b. Calculate the heating vapor consumption and heat transfer area. c. How many kPa is the vacuum applied to the system?
