Consider a surface at 0oC that may be assumed to be a blackbody in an environment at . If of radiation is incident on the surface, the radiosity of this black surface is
- a)0 W/m2
- b)15 w/m2
- c)314.94 W/m2
- d)300 W/m2
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
Consider a surface at 0oC that may be assumed to be a blackbody in an ...
By definition radiosity is the rate at which a thermal radiation levels a surface per unit area
Ga = 300 W/m2
As surface is black, it completely absorbs the radiation incident on it,
Therefore
Gr = 0
By Stefan Boltzmann Law
Eb = σT4
= 5.67 x 10-8 x 2734
Eb = 314.94 W/m2
Radiosity is given as
J = Eb +Gr
J = 314.94 W/m2
Note that Eb>G because the difference Eb - Ga must be equal to rate of heat convection from the environment to surface.
