= Consider the one-dimensional steady heat conduction around the rod shown figure. The rod has a uniform cross-sectional area A = 0.02 m, perimeter P = 0.6 m, and length L = 1 m. One extreme of the rod (x = L) is kept at temperature Twall - 400K, while the other end of the rod (x=0) is insulated. Additionally, an insulation layer of length 0.4 m (along the x direction) is wrapped around the rod so that convection with the ambient is inhibited. The ambient temperature is at 100K and the heat transfer coefficient h with the exposed section of the rod is found to be h = 0.4 kW/mK. The thermal conductivity of the rod is k = 500 W/(mK).
