A triangular fin having a thermal conductivity of $\mathrm{k}=15\mathrm{W}/\mathrm{m}.\mathrm{K}$ is attached to a heated surface with a temperature of $25^{?}\mathrm{C}$. The ambient air is $100^{?}\mathrm{C}$ and the convective heat transfer coefficient is $h=120\mathrm{W}/{\mathrm{m}}^2.\mathrm{K}$ The fin is $100\mathrm{mm}$ long and the thickness at the base is $t_o=50\mathrm{mm}$. Using five equal partitions ( 7 temperature points) to solve this problem. (1) What are the temperature equations for point 1 to 7 ? (3 points) (2) What are the temperature values for point 1 to 7 ? (3 points) (3) What is the heat transfer rate from the fin to the surrounding environments? ( 1 point)
