A pin fin of uniform cross-sectional area is fabricated of an aluminum alloy (k = 160W m-1 K-1 ). The fin diameter is D = 4 mm,
and the fin is exposed to convective conditions characterized by h = 220W m-2 K-1 . It is reported that the fin efficiency is ?f = 0.65. Account for convection heat transfer at the fin tip.
Questions: (a) What is the length of the fin, L?
(b) What is the fin effectiveness ?f?
