Q. 55 In a simple concentric shaft-bearing arrangement, the lubricant flows in the 2
mm gap between the shaft and the bearing. The flow may be assumed to be a
plane Couette flow with zero pressure gradient. The diameter of the shaft is 100
mm and its tangential speed is 10 m/s. The dynamic viscosity of the lubricant is
0.1 kg/m.s. The frictional resisting force (in newton) per 100 mm length of the
bearing is _____
