Question

what are the fundamental assumptions needed to apply heat transfer, radiation circuit analysis theory?

DI Question 3 8 pts Select any of the assumptions listed below that are always required when developing a radiation network analysis. O Highly reflective surfaces Non-participating medium Opaque surfaces O Insulated surfaces O Gray surfaces DI Question 4 8 pts The figure below is the sp blackbody (solid line) at 500 K, and for a real surface (dashed line) at the same temperature as the blackbody. Select the spectral emissivity distribution of the rnl urfce frous ectral emissive power E as a function of wavelength, A, for both a

Answer 1

the assumption that are always required in radiation network analysis is gray surface.

Gray surface means the monochromatic emissivity of body is independent of wavelength of incident radiation
