Problem 3 (30 pts.) A Couette flow is approximated by a rotating circular shaft inside a stationary circular bearing. The shaft is 1 m long and 5 cm in diameter. The gap between the rotating shaft and the stationary (fixed) bearing is 2 mm. The gap is completely filled with engine oil (unused) at temperature T = 120°C. Assume linear profile of the velocity distribution. Calculate the power required to rotate the shaft at 500 rpm 2 mm Rotating shaft 50 mm Rotating shaft oil Fixed bearing 1 m
