A 7 cm diameter bed on a 25 cm long bed, as shown in the figure below. The shaft rotates at 3200 revolutions per minute with uniform intervals of 0.2 mm. Continuous operation
The temperatures of the shaft and bearing adjacent to the oil gap are 55 0C. your oil
viscosity 0.05 N. s/m2

and its thermal conductivity is 0.17 W/m. K. Continuity, momentum and

by simplifying the energy equations and solving for each separately,

a) The maximum temperature of the oil,
b) Calculate the heat transfer rates to the bearing and shaft.
