An average convective heat transfer coefficient for flow of 100 °C air over a flat plate is measured by observing the temperature-time history of a 30 mm thick copper slab (p =9000 kg/m2, e air. In one test run, the initial temperature of the plate was 210 °C, and in 5 minutes the temperature decreased by 40°C. Find the heat transfer coefficient for this case. Neglect internal thermal resistance. [Ans. 77 24 W/m2 °C] c 0.38 kJ/kg °C, k-370 W/m°C). exposed to 100 °C
