Students have asked these similar questions

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 1133°C with a convection heat transfer coefficient of 538 W/m²K. The base of the turbine blade maintains a constant temperature of 450°C and the tip is adiabatic. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Hot gas h=538 W/m²K TL E= Turbine blade k = 17 W/m-K p=11 cm, L=5.3 cm A = 5.13cm² T=450°C Determine the temperature at the tip of the turbine blade. The temperature at the tip of the turbine blade is °C.
