Afeed solution of 10,000 lbm at 130°f containing 47.0 lb feso4/100 lb water is cooled to 80°f, where feso4 7h20 crystals are removed. the solubility of the salt is 30.5 lb feso4/100 lb water. the average heat capacity of the feed solution is 0.70 btu/lbm- f. the heat of solution at 18°c is -28.47 btu/lbm feso4 7h20 crystals. if 5% of the water in the feed is vaporized, calculate the yield of crystals and the amount of heat removed from the crystallizer.
