A 12,000 pounds of a 40% MgSO4, solution at 210F is fed to a Swenson-Walker Cooling Crystallizer per hour. The magma from the erystallizer was found to be 70F. The cooling water is fed at 60F and comes out at 95F. The overall heat transfer coefficient of the heat exchanger in the crystallizer is estimated to be 120 BTU/(h-ft^2-F). If there is a 3% heat lost to surroundings, calculate the yield of crystals produced (Ibm/h). heat transfer area (ft), and the rate of cooling water required in gal/min.
