Calculate maximum heat lost (qmax) in Watt by the fin. An aluminum fin with a thickness of 1.0 mm and a thermal conductivity (k) of 205 W/m-C is attached to a circular tube with an outer diameter of 3.0 cm. The fin has a length of 7 mm. The tube wall is maintained at a temperature of 120C, while the surrounding environment temperature is 20C. The convection heat transfer coefficient between the fin and the environment is 15 W/m2. C. The fin efficiency value is 0.945.
