The figure shows a spray dryer operating at steady state. The mixture of liquid water and suspended solid particles entering through the spray head contains 30% solid particles by mass. Dry air enters at 177°C, 1 atm, and moist air exit at 85°C, 1 atm, and 21% relative humidity with a volumetric flow rate of 310 m3/min. The dried particles exit separately. Determine: the volumetric flow rate of the entering dry air, in m3/min. the rate that dried particles exit, in kg/min.
