Product description
3.13. Calculate and compare the sedimentation rates of Al2O3 particles in water in gravitational and centrifugal fields under the following conditions: particle radius r = 5 * 10–7 m; the density of the dispersed phase p = 3.9 * 103
kg / m3; the density of the dispersion medium p0 = 1.103 kg / m3; viscosity n = 1 * 10–3 Pa * s; centrifugal acceleration w ^ 2 h = 300g.
