The latent heat load in an auditorium is 25% of the sensible heat load...
Explanation:
In the given question, we are asked to find the value of the sensible heat factor (SHF) based on the information that the latent heat load in an auditorium is 25% of the sensible heat load.
Latent Heat Load:
The latent heat load refers to the heat energy required to change the state of a substance without changing its temperature. In the case of an auditorium, this can include the heat energy required for the evaporation of moisture from the occupants, as well as any other latent heat sources.
Sensible Heat Load:
The sensible heat load refers to the heat energy required to change the temperature of a substance without changing its state. In the case of an auditorium, this can include the heat energy required for heating or cooling the air, as well as any other sensible heat sources.
Relationship between Latent Heat Load and Sensible Heat Load:
According to the given information, the latent heat load is 25% of the sensible heat load. This means that the amount of heat energy required for latent heat purposes is one-fourth (25%) of the amount of heat energy required for sensible heat purposes.
Formula for Sensible Heat Factor (SHF):
The sensible heat factor (SHF) is the ratio of the sensible heat load to the total heat load. It is given by the formula:
SHF = Sensible Heat Load / Total Heat Load
Calculation:
Let's assume the sensible heat load to be "x".
According to the given information, the latent heat load is 25% of the sensible heat load. Therefore, the latent heat load can be expressed as 0.25x.
Total Heat Load = Sensible Heat Load + Latent Heat Load
Total Heat Load = x + 0.25x
Total Heat Load = 1.25x
Now, substituting the values of sensible heat load and total heat load in the formula for SHF, we get:
SHF = x / (1.25x)
SHF = 1 / 1.25
SHF = 0.8
Therefore, the value of the sensible heat factor (SHF) is 0.8.
Hence, the correct answer is option C) 0.8.

Now, substituting the values of sensible heat load and total heat load in the formula for SHF, we get:
SHF = x / (1.25x)
SHF = 1 / 1.25
SHF = 0.8
Therefore, the value of the sensible heat factor (SHF) is 0.8.
Hence, the correct answer is option C) 0.8.
