A hot surface at 150°C is to be cooled by attaching 3-cm-long, 0.25-cm-diameter aluminum pin fins (k = 237 W/m-K) 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/m²K. Determine the rate of heat transfer from the surface for a 1-m × 1-m section of the plate. Also determine the overall
effectiveness of the fins.
