Consider a hot automotive engine, which can be approximated as a 0.5-m-high, 0.40-m-wide, and 0.8-m-long rectangular
block. The bottom surface of the block is at a temperature of 80°C and has an emissivity of 0.95. The ambient
air is at 20°C, and the road surface is at 25°C. Determine the rate of heat transfer from the bottom surface of the engine
block by convection and radiation as the car travels at a velocity of 80 km/h. Assume the flow to be turbulent over the entire
surface because of the constant agitation of the engine block
