143. Solving a chemistry problem

3.3. Calculate the radius of the particles of AgCl sol in water if their settling time in the centrifuge was 10 minutes under the following conditions: initial level h1 = 0.09 m; final level h2 = 0.14 m; the density of the dispersed phase p = 5.6 * 103 kg / m3; the density of the dispersion medium is p0 = 1 * 103 kg / m3; centrifuge rotation speed n = 1000 rpm; viscosity n = 1 * 10–3 Pa * s.
