The figure below shows a spray dryer operating at a steady state. The mixture of liquid water and suspended solid particles entering through the spray head contains 35% solid mass. Dry air enters at 187 deg C, 1 atm, and moist air exits at 87 deg C, 1 atm and 20% relative humidity with a volumetric flow rate of 300 m3/min. The dried particles exit separately. Determine: The Volume flow rate of the entering dry air, Va The rate that dried particles exit, Vp = Solid-liquid mixture 65% liquid. 35% solid Dry air, 187°C, 1 atm kg/min m3/h Moist air 300 m³/min, 90°C, 1 atm, = 20% Dried particles
