Problem 3 – Energy and Entropy Balance application Long cylindrical steel rods (p = 7833 kg/m³ and cp = 0.465 kJ/kg.°C) of 10-cm diameter are heat treated by drawing them at a velocity of 3 m/min through a 7-m-long oven maintained at 900°C. If the rods enter the oven at 30°C and leave at 700°C. Determine: The rate of heat transfer to the rods in the oven, and The rate of entropy generation associated with this heat transfer process.
