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 36% solid matter by mass (at 1).
Dry air enters at 177°C, 1 atm, (at 2) and moist air exits at 85°C,
1 atm, and 21% relative humidity with a volumetric flow rate of 210
m3/min (at 3). The dried particles exit separately (at
4). Determine the mass flow rate of the dried
particles, m4 = mp1.
