A circular rod is rotating within a concentric hollow circular cylinder at 1200RPM, with lubricant existing within the small annular gap between the rod and the cylinder. Given that rod radius=2cm, rod length=6cm, gap size=0.1mm and u=0.2Ns/m?, determine the power required to rotate the circular rod. Assume that the small annular gap is small compared to the radius of the circular rod and as a result, linear velocity distribution exists within the lubricant. [Ans: 95.3W] A circular rod is rotating within a concentric hollow circular cylinder at 1200RPM, with lubricant existing within the small annular gap between the rod and the cylinder.
