A turbine blade made of a metal alloy (k = 17 W/m·K) has a length of 5.3 cm, a perimeter of 11 cm, and a cross-sectional area of 5.13 cm2. The turbine blade is exposed to hot gas from the combustion Chamber at 973°C with a convection heat transfer coefficient of 538 W/m2·K. The base of the turbine blade maintains a constant temperature of 450°C and the tip is adiabatic. Determine the heat transfer rate to the turbine blade and temperature at the tip.
