Both ends of a 0.6 cm copper U-shaped rod, as shown in the accompanying sketch, are rigidly
Question:
Both ends of a 0.6 cm copper U-shaped rod, as shown in the accompanying sketch, are rigidly affixed to a vertical wall, the temperature of which is maintained at 93?C. The developed length of the rod is 0.6 m and it is exposed to air at 38?C. The combined radiative and convective heat transfer coefficient for this system is 34 W/(m2 K). (a) Calculate the temperature of the midpoint of the rod. (b) What will the rate of heat transfer from the rod be?GIVENU-shaped copper rod rigidly affixed to a wallDiameter (D) = 0.6 cm = 0.006 mDeveloped length (L) = 0.6 mWall temperature is constant at (Ts) = 93?CAir temperature (T??) = 38?CHeat transfer coefficient ( h ) = 34 W/(m2 K)ASSUMPTIONSThe system is in steady stateVariation in the thermal conductivity of copper is negligibleThe U-shaped rod can be approximated by a straight rod of equal lengthUniform temperature across any section of therod
