Consider a gas turbine blade of 1 mm thickness, made of super alloy with k = 20 W/m·K. The blade is attached to a base and exposed to hot gases on the other side. The convective heat transfer coefficient between the blade and the gas is 1500 W/m2·K. If the temperature of the gas is 1200°C and that of the base is 900°C, the temperature (in °C) of the exposed surface of the blade is _______
Correct : 916.7
