is 4mm in diameter and 500mm long with thermal conductivity of 300W/(mC). It is exposed to a stream of air at 25C with convection coefficient of 20W/(m2C). Neglect the heat loss from the tip of the fin. Determine a) heat loss from the fin b) efficiency of the fin c) effectiveness of the fin Would you suggest increasing the length of this fin to increase the heat transfer? Justify. (Do not use chart for the calculations.) [12 Marks]
