The flow of oil (k=0.145 w/m. k, µ= 0.605 kg/m. s = 0.605 n. s/m2 ) in a journal bearing can be treated as parallel flow between two large isothermal plates with one plate moving and the other stationary. consider two such plates are separated by 0.7 mm thick oil film. the upper plate moves at a constant velocity 8 m/s, while the lower plate is stationary. the temperatures of the upper and lower plates are 40°c and 15°c, respectively. a. obtain relations for the velocity and temperature distributions in the oil. (15 points) b. determine the maximum temperature and where it occurs, and (15 points) c. the heat flux from the oil to each plate. (10 points)

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
