W Suppose that a finned surface is exposed to an environment with a temperature of 26 °C and a convection heat transfer coefficient of 27 m². K The thermal conductivity, perimeter, and cross-sectional area of the fin are 147 W 101 mm, and 5.2 cm2, respectively. The temperature of the fin base is kept constant at 295.3 °C. In practice, recommend what should m. K be the fin length in millimeters that will provide a good compromise between having an economical fin design and a reasonable rate of heat transfer from the fin.
