How is the required exhaust rate calculated for the High Bay area?

The required exhaust rate for a High Bay area is calculated by multiplying the square footage of the area by a specific airflow rate, typically expressed in cubic feet per minute (CFM) per square foot. Option B highlights this method, using a factor of 1.5 CFM per square foot, which is a common industry standard for spaces requiring adequate ventilation due to heat, odors, or other airborne contaminants typically found in high bay areas.

This calculation ensures that the exhaust system can effectively remove any generated pollutants or heat, maintaining air quality and comfort levels. The chosen factor can vary based on the specific application or local codes, but the principle remains consistent: relate the area size directly to the exhaust requirements, allowing for an effective and efficient design of ventilation systems.

Understanding the required exhaust rate through this calculation is crucial for architects and engineers to ensure safety and compliance with health standards in high bay environments.
