A falling ball viscometer is sometimes used to determine the viscosity of a fluid. In a particular set-up, a stainless steel ball (d = 0.2 mm, rho = 8000 kg/m^3) is dropped into a large container of oil (v = 1.33 times 10^-5 m^2/s). If the ball travels 75 mm in 5.45 s under steady state conditions, the viscosity of the oil is: Select one: a. 0.01.13 Pa.s; b. 0.106 Pa.s; C. 1.17 Pa.s d. 13.6 Pa.s
