Question:
Consider a hot antomotive engine, which can be approximated as a 0.5m high, 0.4m wide and 0.8m long rectangtalar block. The bottom surface of the block is at temperature of 80^(')C and has an emissivity of 0.95 , The ambient air temperature is at 20^(@)C and the road surface is at 25^(@)C. Assume the flow to be turbulent bver the entire surface of the engine block and the car travels at velocity of 80km//h, it is required to: (a) Sketch the problem and show data 2U U (b) Determine the heat transfer coefficient for the bottom surtace of the engine block [3 marks] (c) Determine the average heat transfer from the bottom surface of the engine block by
