The rod of 1-in. radius shown in Figure P13–4 generates heat internally at the rate of uniform Q = 10;000 Btu/(h-ft³) throughout the rod. The left edge and perimeter of the rod are insulated, and the right edge is exposed to an environment of T_∞ = 100 ° F. The convection heat-transfer coefficient between the wall and the environment is h = 100 Btu/(h-ft²-° F). The thermal conductivity of the rod is K_xx = 12 Btu/(h-ft-°F). The length of the rod is 3 in. Calculate the temperature distribution in the rod. Use at least three elements in your finite element model.
