Pr.5 (30 points) A circular pin fin made from aluminium ally (k = 180), 0.6 cm in diameter and 10 cm long extends horizontally into atmospheric air at 50 °C from a heat source at 150 °C. Assume adiabatic fin tip, select from Table 3.4 in chapter3 the suitable equation to solve this problem: a) Draw a complete schematic. b) Estimate the rate of heat transfer between the fin and the air. Assume Tav = 130 °C. Check this assumption during your calculation using equation (A) below: tanh mL If = T.+(T. -T.) (A) mL
