3. The steel ball (density ρ ´= 9 g / cm3) with a diameter d = 0.8 cm with constant speed falls in castor oil (density ρ = 0,96 g / cm3, and a dynamic viscosity η = 0,99 Pa • s) . Given that the critical Reynolds number Rekr = 0.5, determine the nature of the movement of oil, due to the fall in its bulb.
