A potassium chloride crystallizer that operates at 100F has a fines dissolution loop where the slurry temperature

Question:

A potassium chloride crystallizer that operates at 100°F has a fines dissolution loop where the slurry temperature is 130°F. The solubility of KCI is 39.3 g/100 g H2O at 100°F and 44 g/100 g H2O at 130°F. 

(a) If the solution is initially supersaturated by to dissolve 10-μm crystals or 50-μm crystals if the change in solution concentration 1.0 g/100 g and the temperature is suddenly increased to 130°F, how long will it take is neglected? 

(b) If the average crystal size in the fines loop 200 μm and the slurry has 30 g solid/L, how close to saturation will the solution be after 10 s at 130°F?
