    Measurement of the spectral, directional absorptivity of a certain non-reflecting surface shows that directional and spectral dependencies may be model as the product of two independent functions: This surface is irradiated by diffuse blackbody radiation at a temperature of 5800 K. Note that the intensity of ideal radiation can be calculated at Ib= Eb/pi(W/m2 -sr). The surface is at a uniform temperature of 300 K. Determine the rate that energy is absorbed by the surface (W/m2 ) Determine the net...

  • How much power (power is the energy per second) is radiated by the person

    Radiation of Energy The rate of heat transfer by emitted radiation is determined by the Stefan-Boltzmann law of radiation: = aeAT4 where o 5.67x10-8 J/s - m2 K is the Stefan-Boltzmann constant, A is the surface area of the object, and T is its absolute temperature in kelvin. The symbol e stands for the emissivity of the object, which is a measure of how well it radiates An ideal jet-black (or black body) radiator has e 1,whereas a perfect reflector has...
