The sensible heat factor during the heating and humidification process is given by (where h1 = Enthalpy of air entering the heating coil, h2 = Enthalpy of air leaving the heating coil and hA = Enthalpy of air at the end of humidification process)
A. $$\frac{{{{\text{h}}_{\text{A}}} - {{\text{h}}_2}}}{{{{\text{h}}_1} - {{\text{h}}_2}}}$$
B. $$\frac{{{{\text{h}}_2} - {{\text{h}}_{\text{A}}}}}{{{{\text{h}}_1} - {{\text{h}}_2}}}$$
C. $$\frac{{{{\text{h}}_1} - {{\text{h}}_2}}}{{{{\text{h}}_{\text{A}}} - {{\text{h}}_2}}}$$
D. $$\frac{{{{\text{h}}_{\text{A}}} - {{\text{h}}_1}}}{{{{\text{h}}_2} - {{\text{h}}_1}}}$$
Answer: Option D
Solution (By Examveda Team)
The sensible heat factor during the heating and humidification process is given by $$\frac{{{{\text{h}}_{\text{A}}} - {{\text{h}}_1}}}{{{{\text{h}}_2} - {{\text{h}}_1}}}$$This Question Belongs to Mechanical Engineering >> Refrigeration And Air Conditioning
this is wrong answer
sensible heat factor is defiend as the ratio of sensible heat added (h2-h1) to total heat added (hA-h1) so D option can be true if reciprocal is taken
Sensible heat factor=sensible heat/ total heat.
Sensible heat = h2-h1 and total heat= hA-h1.
SHF during heating and
humidification =(h2-h1)/(hA-h1)
