The spectral reflectivity distribution for white
Chapter 12, Problem 12.51(choose chapter or problem)
The spectral reflectivity distribution for white paint(Figure 12.22) can be approximated by the followingstair-step function:?(?m)?0.4 0.43.0?3.0??0.75 0.150.96A small flat plate coated with this paint is suspendedinside a large enclosure, and its temperature is main-tained at 400 K. The surface of the enclosure is maintained at 3000 K and the spectral distribution ofits emissivity has the following characteristics:?(?m)?2.0?2.0??0.2 0.9(a) Determine the total emissivity, ?, of the enclosuresurface.(b) Determine the total emissivity, ?, and absorptivity,?, of the plate.
