Application Of Stefan Boltzmann Law

The Stefan Boltzman Law gives the flux from a hot source as E=epsilon*sigma*T^4, where epsilon is the emissivity and T is the temperature in Kelvins and sigma is a constant 5.67e-8 W-m^2/K^-4. For a black body epsilon is 1.0 and for a reflective surface epsilon is small. IR warming lamps are one of the applications of the SB Law. The power required can be calculated from the mass and specific heat of the food, the required rate of heating, and the rate of heat loss by conduction and convection.
