A feed solution of 10000 lbm at 130°F containing 47.0 lb FeSO₄
per 100 lb water is cooled to 80°F, where FeSO₄•7H₂O crystals are removed. The solubility of the salt is 30.5 lb FeSO₄
per 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 –4.4 kcal/gmol FeSO₄•7H₂O, Calculate the yield of crystals and make a heat balance. Assume that no water is vaporized.
