In the steam generation process represented in the figure, it is desired to produce 350,000 pounds of steam/hour in the boiler to feed them to the evaporators. in the evaporators it loses 25% of the steam to the atmosphere, while the rest is condensed and recycled to the boiler. In evaporators, however, for every 25 pounds of condensate that is recycled, one pound of a solution containing 1% dissolved solids. If the fresh feed water contains 150 ppm dissolved solids and the inlet to the boiler must not contain more than 350 ppm of solids, find:

i) The pounds of water fed. ii) Recirculated pounds per hour and their composition. iii) The amount of purge and its composition.
