17.44 Heat from a flat wall is to be enhanced by adding straight fins, of constant thickness, made of stainless steel. The following specifications apply: h Tb (base) T∞ (air) = 60 W/m² K = 120°C = 20°C Fin base thickness, t = 6 mm Fin length, L = 20 mm Determine the fin efficiency and heat loss per unit width for the finned surface.
