A 25-mm diamenter shaft is pulled through a cylindrical bearing as shown. The lubricant that fills the 0.3-mm gap between the shaft and bearing is an oil having a kinematic velocity of 8.0x10^-4 m^2/s and a specific gravity of 0.91. Determine the force P required to pull the shaft at a velocity of 3 m/s. Assume the velocity distribution in the gap is linear.

Note: picture not shown but length is 0.5m. This is also question 1.38 in the 4th edition-The one that is poping up is not the right one.
