Practice session

An industrial crystallizer is fed 5,000 kg/h of a 50 wt% sodium sulfate (Na2SO4) solution at 80°C. Upon cooling to 25°C, it produces a wet filter cake containing 90 wt% dry Na2SO4 crystals and 10 wt% entrained mother liquor. The saturated mother liquor contains 25 wt% dissolved Na2SO4. Assuming steady-state operation without evaporation, what is the hourly production rate of the wet filter cake?
