A fin has 5 mm diameter and 100 mm length. The thermal conductivity of fin material is 400 Wm−1K−1. One end of the fin is maintained at 130∘C and its remaining surface is exposed to ambient air at 30∘C. If the convective heat transfer coefficient is 40 Wm−2K−1, the heat loss (in W) from the fin is |
