A metal rod is attached horizontally to a large tank at a temperature of 2000C. The rod has 1 cm diameter, 30 cm length and thermal conductivity of 65 W/mK. The rod dissipates heat by convection into the ambient air at 200C with heat transfer coefficient of 15 W/m2K. What is the temperature of the rod at 10 cm and 20 cm from the tank? Assuming the rod as a long fin, Calculate the heat transfer rate, the fin efficiency and effectiveness.
