322. Calculate how many times the sedimentation time of spherical suspension particles differs at a distance of 10 cm in the Earth´s gravity field (g = 9.807 m / s2) and at a similar distance from 5 to 15 cm (from the axis of rotation) in a centrifuge whose rotor rotates with constant speed of 600 s–1. The particle radius is 0.50 µm, the density is 8.10 g/cm3, the medium density is 1.11 g/cm3, and its viscosity is 2.02 mPa*s.
