Calculate the efficiency of the PM2.5 WINS, knowing that the particles are spread out over the area of the nozzle. Using the dimensions of an impactor within an ambient PM monitor, calculate the stopping distances within that sampler for PM with aerodynamic diameters of 0.1 m, 0.5 m, 1 m, 2 m, 2.5 m, 3 m, 5 m, 7.5 m, 10 m, 12.5 m, 15 m, 17.5 m, and 20 m. Nozzle diameter = 0.00391 m Jet-to-plate distance = 0.00047 m Hint: Be sure that all of your units match up! What kind of sampler is this? Why? Show all calculations Due: 4/6
