1.- A steel (k=14 W/m K) rod, 18 cm long and 5 mm in diameter has one end maintained at 100 °C. The surface of the rod is exposed to ambient air at 25°C with a convection heat transfer coefficient of 100 W/m2K. If the rod has an adiabatic tip, what is the heat loss in W? Calculate the heat loss if the fin were infinitely long instead.
