29. Solving a chemistry problem

35. When studying the rate of sedimentation of a suspension in a measuring tube, the time of complete sedimentation of the phase was fixed at 1.5 hours. Calculate the minimum particle size if the settling height is 10 cm, the viscosity of the dispersion medium is 1∙10-3 Pa∙s, the density of the dispersed phase and the dispersion medium is 2300 and 1100 kg/m3, respectively.
