The circular fin of diameter D=1mm and length L=25.4mm, made ofcopper (k=400 W/m.K), are used to enhance heat transfer from asurface that is maintained at temperature Tb=132 °C. and the rodhas another end attached to a large surface which is maintained atTe= 0°C. The airflow through the rod surfaces is at T∞ = 0 °C withconvection heat transfer coefficient h = 100 W/m2.K. (Hint: usetable 3.4 in the lecture slides.)
(a) Express temperature T(x) along the fin and calculate thetemperature at x=L/2. (5points)
(b) Determine the rate of heat transfer at the hot end of thefin (3 points) and calculate the fin effectiveness (2 points).
