2. In a test designed to measure the viscosity of an oil, a steel ball bearing of diameter 25mm is dropped from a height into some oil such that the terminal velocity as it passes through the oil is 5.86m/s. a. Given the ball bearing has a density of 7800kg/m3 oil has a density of 920kg/m”, calculate the viscosity of the oil. [6 marks] a b. A section of propeller in an oil pump can be considered to be a wing profile with a chord of 0.035m. Using the values of density and viscosity of the oil from part b. calculate the velocity of oil flow through the pump when the it is about to transition from 'laminar flow' to transitional flow?
