2.36 A turbine blade 6.3 cm long, with cross-sectional area A = 4.6 104 m and perimeter P = 0.12 m, is made of stainless steel (k = 18 W/m K). The temperature of the root, Ts, is 482C. The blade is exposed to a hot gas at 871C, and the heat transfer coefficient his 454 W/m 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. 6.3 cm One turbine blade Hot gas Area = 4.6 104 m 2 Perimeter = 0.12 m
