Dust particles of diameter 0.06 mm and density 1.6 g/cm are unsettled during high winds and rise to a height of 350 m by the time things calm down. Estimate how long will it take for the dust particles to fall back to the ground in still air at 1 atm and 15°C, and their velocity. Disregard the initial transient period during which the dust particles accelerate their terminal velocity, and assume Stokes law to be applicable. Pe =1.225kg /m', µ =1.802 x 10 kg/m.s
