Q2 : A hot surface at 100°C is to be cooled by attaching 0.25 3 cm long, 0.25 cm diameter aluminum pin fins (k =237 em W/m.°C) to it, with a center-to-center distance of 0.6 cm. The temperature of the surrounding medium is 30 °C, and the heat transfer coefficient on the surfaces is 35 W/m2.°C. Determine the rate of heat transfer from the surface for a 1x1 m2 seetion of the plate. Also determine the overall effectiveness of the fins.
