Dilution Ventilation Rate for Contaminant Control

Proper ventilation is crucial to maintaining air quality and controlling contaminants in an enclosed space. The required airflow (Q) helps in reducing the concentration of airborne contaminants to safe levels.

Key Factors:

• Required Airflow (Q): The necessary airflow to achieve acceptable contaminant concentration.
• Contaminant Generation Rate (G): The rate at which the contaminant is introduced into the air.
• Acceptable Concentration (C_desired): The maximum permissible concentration to ensure safety.
• Ambient Concentration (C_ambient): The current contaminant level before ventilation is applied.

Understanding these factors helps in determining the appropriate ventilation rate to maintain air quality, comply with safety regulations, and create a healthier environment.
