X h, Too w = 1 m A triangular fin having a thermal conductivity of k = 15 W/m.K is attached to a heated surface with a temperature of 25 C. The ambient air is 100 C and the convective heat transfer coefficient is h=120 W/m.K The fin is 100mm long and the thickness at the base is t-50mm. Using five equal partitions (7 temperature points) to solve this problem. What are the temperature equations for point 1 to 7 What are the temperature values for point 1 to 7 What is the heat transfer rate from the fin to the surrounding environments
