A long cylindrical steel rod is heat treated in an oven that is 7 meters long and is maintained at a temperature of 900°C. The rod is 10-cm in diameter and is drawn at a velocity of 3 m/min. The rod enters the oven at 30°C and leave at 700°C. The rod has a density of 7800 kg/m³ and an average heat capacity of 0.465 kJ/kg °C. Calculate the rate of heat transfer to the rods in the oven.
