A turbine blade 6.3 cm long with cross-sectional area A 4.6 x 10-4 m2 and perimeter P 0.12 m, is made of stainless steel (k =18 W/m K). The temperature of the root, Ts, is 482°C. The blade is exposed to a hot gas at 871°C and the heat transfer coefficient h is 484 W/(m^2.K). Determine the temperature of the blade tip and the rate of heat flow at the root of the blade. Assume that the tip is insulated.
