While workers spray paint the ceiling of a room, numerous small paint aerosols are dispersed into the air. Eventually, these particles will settle out and fall to the floor or other surfaces. Consider small spherical paint particles of diameter D = 10 μm and specific gravity of 1.2. Determine the time it would take this particle to fall 2.4 m from near the ceiling to the floor. Assume that the air within the room is motionless.
