What is the sensible heat factor during the heating and humidification process equal to?

Where, H_{1} = Total heat of air entering the heating coil

H_{2} = Total heat of air leaving the heating coil

H_{3} = Total heat of air at the end of the humidification

Option 2 : \(\frac {H_2-H_1}{H_3-H_1}\)

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 = H_{2} - H_{1}

Total heat TH = H_{3} - H_{1}

Therefore,

\(SHF= \frac{{{{\rm{H}}_2} - {{\rm{H}}_1}}}{{{{\rm{H}}_3} - {{\rm{H}}_1}}}\)
