Product description
- Calculate the time for which the spherical particles of glass in water settle at a distance h = 1 cm, if the dispersity of the particles is: a) 0.1 μm-1;
b) 1 μm -1; c) 10 μm -1. The densities of the dispersed phase and the dispersion medium are 2.4 and 1.0 g / cm 3, respectively; the viscosity of the dispersion medium is η = 10 -3 Pa · s.
