Determine the viscosity of the suspension according to the Einstein equation at temperature T, if the concentration of the dispersed phase is c,% (vol). Determine the relative viscosity (Table 10). The particle density of the dispersed phase is ρ, the density of the dispersion medium is ρ0, and the viscosity of the dispersion medium is η0. (for spherical particles α = 2.5).
