Product description
3.2. Calculate and compare the settling time of particles in gravitational and centrifugal fields under the following conditions: particle radius r = 10–7 m; the density of the dispersion phase p = 3 * 103 kg / m3; the density of the dispersion medium p0 = 1 * 103 kg / m3; viscosity n = 1 * 10–3 Pa * s;
settling height N = 0.1 m; centrifugal acceleration 2 h = 200g.
