A pin fin of uniform, cross-sectional area is fabricated of an aluminum alloy ( 160 W/m·K). The fin diameter is 7 mm, and the fin is exposed to convective conditions characterized by 220 W/m2·K. It is reported that the fin efficiency is 0.65. Determine (a) the fin length and the fin effectiveness . Account for tip convection.
