STEADY HEAT CONDUCTION
Characteristic Length:
Efficiency of the Fin:
Efficiencies of circumferential fins of rectangular profile, according to Reference 3Efficiencies of straight rectangular and triangular fins.
Problems: An aluminum fin [k = 200 W/m · ◦C] 3.0 mm thick and 7.5 cm long protrudes from a wall, as in Figure 2-9. The base is maintained at 300◦C, and the ambient temperature is 50◦C with h = 10 W/m2 · ◦C. Calculate the heat loss from the fin per unit depth of material.
