The formula to calculate the fan capacity is:
\[ CFM = \frac{V \times ACH}{60} \]
Where:
Bathroom fan capacity, measured in cubic feet per minute (CFM), refers to the volume of air that the fan can move per minute. This capacity is crucial for ensuring proper ventilation in a bathroom, removing moisture, odors, and airborne contaminants. The required fan capacity depends on the size of the bathroom and the desired air changes per hour (ACH). Proper ventilation helps prevent mold growth and maintains a healthy indoor environment.
Let's assume the following values:
Using the formula:
\[ CFM = \frac{500 \times 8}{60} = \frac{4000}{60} = 66.67 \, \text{cubic feet per minute} \]
The Fan Capacity is 66.67 cubic feet per minute.
Let's assume the following values:
Using the formula:
\[ CFM = \frac{300 \times 10}{60} = \frac{3000}{60} = 50 \, \text{cubic feet per minute} \]
The Fan Capacity is 50 cubic feet per minute.
