6. Solving a chemistry problem

4. Particles of the dispersed phase with a diameter of 1.25 microns settle in the medium at a speed of 4.255*10-5 cm/s. Density of particles 2100 kg/m3, medium 1100 kg/m3. What should be the rotational speed of the centrifuge so that the same particles in the same medium travel a distance of 0.15 to 0.25 m in the same time?
