The flow of oil in a journal bearing can be approximated as parallel flow between
two large plates with one plate moving and the other stationary. Such
flows are known as Couette flow.

Consider two large isothermal plates separated by 2-mm-thick oil film. The upper plates moves at a constant velocity of 12 m/s, while the lower plate is stationary. Both plates are maintained at 20°C.

(a) Obtain relations for the velocity and temperature distributions in the oil.

(b) Determine the maximum temperature in the oil and the heat flux from the oil to each plate
