8. The dispersion composition of the suspension was determined by sedimentation analysis. Determine the average particle radius of the dispersed phase of one of the fractions of the suspension, using the experimental data given in table 8, where the sedimentation rate (U) is given. density of the aqueous dispersed phase (ρ). When calculating the density and viscosity of water, take equal to 1000 kg/m3 and 0.001 Pa*s, respectively.
option number U*104 m/s ρ, kg/m3
9 9.0 2400
When performing this task, pay special attention not only to the calculation formula, but also to the significance of the sedimentation analysis of a suspension as a kind of dispersion analysis of any disperse systems.
