A piece of pipe 0.3048m long weighing 13.34N and having internal diameter of 0.05207m is slipped over a vertical shaft 0.0508m in diameter and allowed to fall. Calculate the approximate velocity attained by the pipe if a film of oil of kinematic viscosity 2.8x 10-5 m2/s and specific gravity 0.92 is maintained between pipe and shaft. Given that drag force and weight will be equal for a constant velocity.
