144. Solving a chemistry problem

3.14. Calculate and compare the sedimentation rates of clay particles in water in gravitational and centrifugal fields under the following conditions: particle radius r = 2 * 10-6 m; settling height H = 0.2 m; the density of the dispersed phase p = 2.7 * 103 kg / m3; the density of the dispersion medium p0 = 1 * 103 kg / m3; viscosity n = 1 * 10–3 Pa * s; centrifuge rotation speed n = 1000 rpm
