3.15. Calculate the speed and time of sedimentation of particles from a height of H = 0.2 m in centrifugal fields of centrifuges with a rotation frequency n of 600 rpm and 6000 rpm. Particle radius r = 2 * 10–6 m; the density of the dispersed phase p = 2.7 * 10 ^ 3 kg / m3; the density of the dispersion medium p0 = 1 * 10 ^ 3 kg / m3; viscosity n = 1 * 10–3 Pa * s.
