Psychrometrics numeric: compute sensible heat factor from sensible and latent rates A process adds sensible heat = 30 kJ/s and latent heat = 20 kJ/s to moist air. Calculate the sensible heat factor (SHF) for the process. Choose the correct value.

Q: Psychrometrics numeric: compute sensible heat factor from sensible and latent rates A process adds sensible heat = 30 kJ/s and latent heat = 20 kJ/s to moist air. Calculate the sensible heat factor (SHF) for the process. Choose the correct value.

Given data Sensible heat rate = 30 kJ/s Latent heat rate = 20 kJ/s Concept/Approach Sensible heat factor: SHF = (Sensible heat) / (Total heat) = S / (S + L). Step-by-step calculation S + L = 30 + 20 = 50 kJ/sSHF = 30 / 50 = 0.60 Final Answer 0.6

Correct Answer: 0.6

Explanation:

Given data

Sensible heat rate = 30 kJ/s
Latent heat rate = 20 kJ/s

Concept/Approach
Sensible heat factor: SHF = (Sensible heat) / (Total heat) = S / (S + L).

Step-by-step calculation
S + L = 30 + 20 = 50 kJ/sSHF = 30 / 50 = 0.60

Final Answer
0.6
