The formula to calculate the CFM per Person (CFMpp) is:
\[ CFM_{pp} = \frac{CFM_{total}}{N} \]
Where:
CFM per person is a measure of the airflow rate provided to each individual in a given space. It is commonly used in HVAC (Heating, Ventilation, and Air Conditioning) systems to ensure adequate ventilation and air quality. The CFM per person value helps in designing systems that can provide sufficient fresh air to occupants, thereby maintaining a healthy and comfortable indoor environment. This metric is crucial for spaces like offices, classrooms, and public buildings where the number of occupants can vary.
Let's assume the following values:
Using the formula:
\[ CFM_{pp} = \frac{1200}{40} = 30 \text{ CFM} \]
The CFM per Person (CFMpp) is 30 CFM.
