139. Solving a chemistry problem

Calculate and compare the sedimentation rate of Al2O3 particles in water in gravitational and centrifugal fields under the following conditions: particle radius r = 5 * 10 ^ -7 m; dispersed phase density ρ = 3.9 * 10 ^ 3 kg / m3; dispersed medium density ρ0 = 1 * 10 ^ 3 kg / m3; viscosity η = 1 * 10 ^ -2 Pa * s; centrifugal acceleration ω ^ 2 h = 300 g
