Решение задачи по физике раздел 30 пункт 29 механика

29. The ball of radius r = 2 mm falls in glycerol at a constant velocity υ = 8,5 mm / s. Determine the Reynolds number Re and the density ρ1, the material of the ball, if the critical Reynolds number Rekp = 0.5. Glycerol density ρ = 1,26 g / cm3, and a dynamic viscosity η = 1,48 glycerol ∙ Pa s.
