PSO

discuss the cooling of a circular fin by means of convective heat transfer along its length. Convection gives rise to a temperature-dependent heat loss or sink term in the governing equation. Shown in Figure 4.9 is a cylindrical fin with uniform crosssectional area A. The base is at a temperature of 100°C (TB) and the end is insulated. The fin is exposed to an ambient temperature of 20°C
