Two metric ton per hour of 30% wt. aqueous MgSO4 solution underwent adiabatic evaporative cooling from 120oF to 80oF to form MgSO4∙7H2O crystals. During cooling, 36 percent of the initial water in the solution was removed. The solubility of MgSO4 at 80oF is 38 g MgSO4 for every 100 g H2O. Some of the mother liquor adhered to the crystals (0.2 kg mother liquor adhering for every kg of crystal hydrate formed) during separation of the solid and liquid phases. 1. What is flow and % composition (MgSO4 and H2O) of the mother liquor stream?
