Two metal rods are being heated in an oven with uniform ambient temperature of 1000°C and convection heat transfer coefficient of 25 W/m2·K. Rod A is made of aluminum (ρ = 2702 kg/m3,cp = 903 J/kg·K, and k = 237 W/m·K) and rod B is made of stainless steel (ρ = 8238 kg/m3, cp = 468 J/kg·K, and k = 13.4 W/m·K). Both rods have diameter of 25 mm and length of 1 m. If the initial temperature of both rods is 15°C, determine the average temperatures of both rods after 5 min elapsed time.
