1. Evaluate the fin efficiency and fin effectiveness for each of the following fin geometries. AIl fins are made of aluminum \( \left(\mathrm{k}=235 \mathrm{~W} / \mathrm{m}-{ }^{\circ} \mathrm{C}\right) \) and are exposed to air at \( 25^{\circ} \mathrm{C} \) with a heat transfer coefficient of \( 154 \mathrm{~W} / \mathrm{m}^{2}-{ }^{\circ} \mathrm{C} \). The base of the fins are at \( 350^{\circ} \mathrm{C} \).
