A flot plato, 0.5 min area, is heated at the rate of 240 W from the bottom. The upper surface is exposed to air at 23.9°C and the surrounding wall temperature is 17.5°C. If the temperature of the upper surface is measured to be 53.7"c, determine the convection heat transfer coefficient between the upper surface and air. Assume the omissivity of the upper surface is 0.89. (The tolerance of your answer is 2%) Answer:
