A continuous single-effect evaporator is to be fed with 5000 kg/hr of solution containing 1 wt% solute. The feed is at temperature of 303K. It is to be concentrated to a solution of 2 wt% solute. The evaporation is at atmospheric pressure (101.3 kPa) and the area of the evaporator is 69.7 m2. Saturated steam is supplied at 143.3 kPa for heating. A.What is the amount of vapor leaving the evaporator in kg/hr? B.What is the amount of steam entering the evaporator in kg/hr?
