A steel plant heat treats steel rods by passing them through a 1000 degrees C oven. The steel rods are 3 meters in length and have a diameter of .020 meters. The steel rods are in the oven for 70 seconds, entering the oven at 30 degrees C and leaving at 800 degrees C. ( Density of steel= 7833 kg/m^3, Cp steel= 0.465 kJ/kg*K)
a.) What is the rate of heat transfer to the rods in the oven?
b.) What is the rate of entropy generation for this heat treating process?
