Oil flow in a journal bearing can be treated as parallel flow between two large isothermal plates with one plate moving at a constant velocity of 5 m/s and the other stationary. Consider such a flow with a uniform spacing of 0.5 mm between the plates. The temperatures of the upper and lower plates are 40°C and 15°C, respectively. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Vm/s The properties of oil at the average temperature of (40+15)/2 = 27.5°C are k = 0.145 W/m-K and = 0.605 kg/m-s = 0.605 N-s/m² By simplifying and solving the continuity, momentum, and energy equations, determine the heat flux from the oil to each plate. The heat flux from the oil to the bottom plate is * 104 W/m² The heat flux from the oil to the top plate is [ * 104 W/m².
