A 29-mm-diameter shaft is pulled through a cylindrical bearing as shown in the figure below. The lubricant that fills the 0.3-mm gap petween the shaft and bearing is an oil having a kinematic viscosity of 8.0 x 104 m2/s and a specific gravity of 0.91. Determine the orce P required to pull the shaft at a velocity of 6 m/s. Assume the velocity distribution in the gap is linear.
