2. Aluminum fins of triangular profile are attached to a plane wall whose surface temperature is 250°C. The fin base thickness is 2 mm, and its length is 6 mm. The system is in ambient air at a temperature of 20°C, and the surface convection coefficient is 40 W/m².K. (a) What are the fin efficiency and effectiveness? (b) What is the heat dissipated per unit width by a single fin?
