Correct Answer - Option 2 :
\(\frac {H_2-H_1}{H_3-H_1}\)
Concept:
Sensible heat, Latent heat and Total heat
- Sensible heat (S.H) is the heat which increases or decreases the temperature of the body.
- Latent heat (L.H) is the heat which is absorbed or released during phase change
- Total heat (T.H) is the sum of sensible heat and latent heat.
T.H = S.H + L.H
Sensible heat factor (S.H.F)
The sensible heat factor is the ratio of sensible heat to total heat.
\(\;\;SHF =\frac{SH}{SH+LH}= \frac{{{\rm{S}}.{\rm{H}}}}{{{\rm{T}}.{\rm{H}}}} \)
Here sensible heat SH = H2 - H1
Total heat TH = H3 - H1
Therefore,
\(SHF= \frac{{{{\rm{H}}_2} - {{\rm{H}}_1}}}{{{{\rm{H}}_3} - {{\rm{H}}_1}}}\)
