8. Consider heat conduction in a uniaxial rod surrounded by a fluid. The right end of the rod is attached to a wall and is at temperature Tr. One half of the bar is insulated as indicated. The free stream temperature is Tf. There is convective heat transfer across the un-insulated surface of the rod as well as over the left end face. Use two equal-length elements to determine the temperature distribution in the rod. Use the following numerical values: L = 0.2 m, k =

200W/m/0C, h = 36W/m2/°C, TR = 600oC, 7} = 300oC, A = lO"4 m2, andP = 0.04m.
