A straight fin fabricated from 2024 aluminum alloy ( 185 W/m·K) has a base thickness of 3 mm and a length of 15 mm. Its base temperature is 100°C, and it is exposed to a fluid for which [infinity] 20°C and 50 W/m2·K. For the foregoing conditions and a fin of unit width, compare the fin heat rate, efficiency, and volume for rectangular, triangular, and parabolic profiles.
