Product description
Calculate the root-mean-square shift ∆x of spherical sand particles (SiO2) in water for 1 sec, as well as the sedimentation rate under the following conditions: temperature Т=293 K, viscosity of the dispersion medium η=1*10-3 Pa*s, sand density rd.f \u003d 2 * 103 kg / m3, density of the dispersion medium rd.s. \u003d 1 * 10-3 kg / m3. Compare the sedimentation stability of disperse systems with particle sizes of 1*10-5 m (coarsely dispersed system) and 1*10-5 m (colloidal solution).
