In a psychrometric process, the sensible heat added is 30 kJ/sec and latent heat added is 20 kJ/sec. The sensible heat factor for the process is1. 0.32. 0.63. 0.674. 1.5

Answer» Correct Answer - Option 2 : 0.6

Concept:

SHF (Sensible Heat Factor):

It is defined as a sensible heat load divided by total heat load.

\({{S}}.{{H}}.{{F}} = \frac{{{{S}}.{{H}}}}{{{{T}}.{{H}}}}=\frac{S.H}{S.H\;+\;L.H}\)

where, T.H = S.H + L.H

S.H = Sensible heat, T.H = Total heat, L.H ⇒ Latent heat 

Calculation:

Given:

S.H = 30 kJ/sec, L.H = 20 kJ/sec

\({{S}}.{{H}}.{{F}} =\frac{S.H}{S.H\;+\;L.H}\)

\({\rm{S}}.{\rm{H}}.{\rm{F}} = \frac{{30}}{{30 + 20}} = \frac{3}{5} = 0.60\;\)
