A 10 wt % aqueous solution of sodium chloride is fed to an evaporative crystallizer which operates at 80o C. The product is a slurry of solute crystals suspended in a saturated solution. The unit is to produce 1000 kg/crystals per hour. If the pump that handles the slurry cannot handle more than 40 wt % solids, find the feed rate to the crystallizer and the evaporation rate of the water. (20 pts)
