A straight fin with a uniform circular cross-sectional geometry
has a length L = 69 mm and diameter D = 4 mm. Convective
heat transfer occurs from all exposed surfaces including the
fin tip at a surrounding air temperature To = 30 °C and a
convective heat transfer cdefficient h = 11 W/(m2K). Fin
thermal conductivity is k = 60 W/(mK) and fin base
temperature is Tb = 70 °C. What is the fin efficiency? (Note:
Answer should be between 0 and 1.)
