Consider an impactor with a rectangular slit, 5 mm wide by 5

Consider an impactor with a rectangular slit, 5 mm wide by 5 cm long, placed at a distance of 12.5 mm from the impaction surface. The impactor is used to collect uranium oxide aerosols of 2 um in diameter. The density of uranium oxide is 10 g/cm. What is the minimum jet velocity needed for collecting the particles? What is the corresponding volumetric sampling flow rate of the impactor under these conditions?
