3. Determine the particle diameter of the aerosol by the ultramicroscopy method in the flow: in the volume W = 2,2 × 10 -19 m 3 87 spherical particles of the aerosol - the smoke of the open-hearth furnaces are counted. The aerosol concentration is C = 1 × 10 -4 kg / m 3; the density of the dispersed phase is ρ = 2⋅10 3 kg / m 3.
