A continuous single-effect evaporator is to be fed with 5000 kg/hr of solution containing 1 wt% solute, the feed is at a temperature of 303 K. 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. It is assumed that the Cp of feed is the same with that of water which is 4.1 kj/kg-K. Assume no BPR. Calculate: a. amount of steam entering the evaporator
