The skin temperature of a nude person is 34.0∘C and the surroundings are at 20.5∘C. The emissivity of skin is 0.905, and the surface area of the person is 1.55 m2. What is the rate P at which energy radiates from the person?
A 2.1-m-long, 0.2-cm-diameter electrical wire extends across a room that is maintained at 20°C. Heat is generated in the wire as a result of resistance heating, and the surface temperature of the wire is measured to be 180°C in steady operation. Also, the voltage drop and electric current through the wire are measured to be 110 V and 3 A, respectively. Disregarding any heat transfer by radiation, determine the convection heat transfer coefficient for heat transfer between the outer surface of the wire and the air in the room.
The tungsten filament of an incandescent light bulb has a temperature of approximately 3000 K. The emissivity of tungsten is approximately 1/3, and you may assume that it is independent of wavelength. If the bulb gives off a total of 100 watts, what is the surface area of its filament in square millimeters?
