3. Consider two large isothermal plates separated by 2-mm thick oil film. The upper plate moves as a constant velocity of 12 m/s, while the lower plate is stationary. Both plates are maintained at 24 °C. (50 points) a. Obtain relations for the velocity and temperature distribution in the oil b. Determine the maximum temperature in the oil and the heat flux from the oil to each plate. Properties: k= 0.145 W/mK u= 0.8374 kg/ms =0,8374 Ns/m 3.
