An oil containing mist of flowrate 3.5 x 10 -3 m3/s is flowing through a tube 0.02 m in diameter. The aerosol comprises equal portions by mass of 3 and 5 micron diameter oil droplets in air at standard conditions. The smaller particles are settling at a rate of 1.5 x 10-4 m/s with the larger particles settling at 2.5 x 10-4 m/s. Are conditions laminar for both the mist and the oil particles?
