Question

A hot surface at 100c 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 30c and the heat transfer coefficient on the surfaces is 35 w/m2k. Determine the rate of heat transfer from the surface 1 m 1 m section of the plate. Determine the percentage enhancement in heat transfer due to the addition of fins.
