7-137 Long cylindrical steel rods (r = 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 a) the rate of heat transfer to the rods in the oven and b) the rate of entropy generation associated with this heat transfer process. | |
