Solar radiation is incident on a semitransparent body at a rate of . If of this incident radiation is reflected back and is transmitted across the body, the absorptivity of the body is
- a)0
- b)0.25
- c)0.30
- d)0.45
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Solar radiation is incident on a semitransparent body at a rate of . I...
G = 500 W/m2 Gr = 150 W/m2
Gt = 225 W/m2
By energy conservation principle,
Ga+Ge+Gt = G
Where Ga = absorbed radiation
Gr = reflected radiation
Gt = transmitted radiation
G = incident radiation
= transmissivity
α = 1-0.3 - 0.45 = 0.25

Explanation:
The given data is:
Incident solar radiation =
Reflected radiation =
Transmitted radiation =
The energy balance equation can be written as:
= + +
where,
= Absorbed radiation
= Reflected radiation
= Transmitted radiation
Given,
=
Substituting the values in the energy balance equation,
= + +
= + +
Dividing the equation by ,
= + +
The absorptivity of the body is given by the ratio of absorbed radiation to the incident radiation, i.e.,
=
Substituting the values of and , we get
=
=
Therefore, the absorptivity of the body is 0.25 or 25%.
Hence, the correct answer is option B (0.25).
