Evaluate the total heat losses per unit length from the rod. Energy is generated in a long circular rod that has a diameter of 10 cm; located in a room. Under steady state condition the surface temperature of the rod is 277C, and its surface emissivity is 0.75. The surrounding air and the room wall temperature are at 27C. The convective natural heat transfer coefficient from the rod surface to the surrounding air is 10 W/m2K.
