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