The tungsten filament in a lamp has a diameter of 0.003 in and is 6-in long. When it is maintained at 2900K, what is the amount of energy emitted by the filament if the emissivity of the filament is 0.3? If the surroundings are at 20oC, what is the electrical power supply to the filament? Assume all the heat transfer is by radiation only.
