QUESTION 2: STEADY HEAT CONDUCTION [24] A hot surface at 100∘C is to be cooled by attaching 30 mm-long, 2.5 mm-diameter aluminium pin fins (k=237 W/m⋅K) to it, with a center-to-center distance of 6 mm. The temperature of the surrounding medium is 30∘C, and the heat transfer coefficient on the surfaces is 35 W/m2⋅K 2.1 Determine the rate of heat transfer from the surface for a 1 m×1 m section of the plate. (20) 2.2 Also determine the overall effectiveness of the fins. (4) Figure 2: Surface with aluminium fins
