I prefer handwritten solutions.arrow_forwardConsider a constant area semi-infinite fin of a circular cross section of radius r. and thermal conductivity k. The base is maintained at T. and the surface of the fin exchanges heat by convection to an ambient fluid at T with a heat transfer coefficient h. It is desired to increase the heat transfer from the fin. The following suggestions are made: (i) doubling k, (ii) doubling ro, (iii) doubling h. Which suggestion will bring about the largest increase in heat transfer? To x h, T C A h, Tarrow_forwardA 20 cm long 304 stainless steel bar is initially at 18°C.

- 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.
