The American University Operations And Supply Chain Management Assignment Help - The extent

Question - The extent 10 which the tip condition affects the thermal performance of a fin depends on the fin
geometry and thermal conductivity, as well as the convection coefficient. Consider an alloyed
aluminum (k = 180 W/m · K) rectangular fin of length L = 10 mm, thickness t = 1 mm, and width w t.
The base temperature of the fin is Tb = 100°C, and the fin is exposed to a fluid M temperature T8 =
25°C.
(a) Assuming a uniform convection coefficient of h = 100 W/m2 · K over the entire fin surface,
determine the fin heat transfer rate per unit width qf, efficiency ?f' effectiveness ef' thermal resistance
per unit width Rt,f' and the tip temperature T(L) for Cases A and B of Table 3.4. Contrast your results
with those based on an inf ...Read More inite fin approximation.
