2-66 One end of a copper rod 30 cm long is firmly connected to a wall that is maintained at 200°C. The other end is firmly connected to a wall that is maintained at 93°C. Air is blown across the rod so that a heat-transfer coefficient of 17 W/m2 .°C is maintained. The diameter of the rod is 12.5 mm. The temperature of the air is 38°c. What is the net heat lost to the air in watts?
