2) Consider an aerosol consisting of particles with densities of 1.0 g cm in air at 1 atm and 20 C. a) What is the diameter of the smallest particles for which Stokes law (without the Cunningham Correction) yields a diffusion coefficient that is correct to within 5%? b) What is the diameter of the largest particle for which Stokes law yields a gravitational settling velocity that is correct to within 5%
