Question

A 50 cm long cylindrical rod with a diameter of 10 cm is attached to a heater on one end, where the temperature is 1000°C. The other end of the cylindrical rod is at 600°C and is exposed to air at 25 °C. The length of the rod is very well insulated. The convection heat transfer coefficient between the end of the rod and the surrounding air is 20 W/m²K and the rod has an emissivity of 0.75. Heater Rod, ? = 0.75 T = 1000 °C T = 25 °C h = 20 W/m²K T = 600 °C a) How much heat is generated by the heater per second?
