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_forward
- A 20 cm long 304 stainless steel bar is initially at 18°C. One end of the bar is suddenly maintained at 100°C. Assuming that your finger can tolerate a 60°C temperature, what is the longest time you are willing to wait before you touch the other end? Be on the safe side and select a conservative model. h,T oil bath glass ballarrow_forwardSmall glass balls of radius 1.1 mm are cooled in an oil bath at 22°C. The balls enter the bath at 180°C and are moved through on a conveyor belt. The estimated heat transfer coefficient is 75 W/m²-ºC. What should the conveyor speed be so that the balls leave at 40°C?

I prefer handwritten solutions.arrow_forwardA 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.
