3.19 A stream of air at 25C and 1atm is laden with particulate matter (unit density spheres) of only two sizes: 1m and 5m. The stream flows through a pipe at an average velocity of 20m/s. The pipe exhausts into a water mist scrubber where the water droplets average 100m in diameter. Based only on a comparison of their impaction numbers, what will be the ratio of particles collected (5m to 1m)
