Analytical Heat Transfer
exposed to an air stream at 20 ◦ C with a heat transfer coefficient
of 200 W/m 2 K. Find the time required for the copper rod to cool
to an average temperature of 25 ◦ C. Write all assumptions if necessary. Thermal conductivity, specific heat, and density of copper
are 401 W/m K, 385 J/kg K, and 8933 kg/m 3 , respectively.
