Consider two fin shapes. One has rectangular cross-section, with width w=40mm and thickness d = 8.0 mm, and the other has circular cross-section, with diameter D=20.2mm (thus, the two fins have identical cross-sectional area Ac).
Both fins have length L. Suppose that both fins have base temperature Tb=318K, and are subject to weak convection in air, with convective heat transfer coefficient h=20 W/m2K and air temperature T∞=290K.
Assume that the tip of each fin is adiabatic. (i.e. there’s no con...
