## FAQs about Air Flow Conversion

### How do you calculate airflow?

To find airflow through a vent or air filter, multiply the air velocity in meters per second by 3600 to get airflow per hour. Then, multiply this result by the vent/filter area (height multiplied by width for a rectangular shape).

The equation is as follows: Airflow = ((air velocity (m/s) x 3600) x (height (mm) x width (mm))

### How much airflow is required for the average size UK bedroom?

The recommended airflow for an average-sized UK bedroom is generally around 10 to 20 cubic feet per minute (CFM) for ventilation purposes. This can vary based on factors like room occupancy, outdoor air quality, and specific ventilation needs.

### What is airflow rate?

Airflow rate refers to the volume of air that moves through a specific point in a given period. It is typically measured in terms of volume per unit of time, such as cubic feet per minute (CFM) or cubic meters per hour. Airflow rate is a crucial parameter in various applications, including HVAC (Heating, Ventilation, and Air Conditioning) systems, industrial processes, and environmental monitoring. In different contexts, airflow rate may be used to assess ventilation, cooling, or the efficiency of air circulation in a particular space or system.

### What is air velocity?

Air velocity is the speed or rate at which air moves in a particular direction. It is typically measured in meters per second (m/s). In the context of ventilation or airflow, air velocity provides information about how quickly air is flowing through a specific area or duct. Understanding air velocity is crucial in HVAC (Heating, Ventilation, and Air Conditioning) systems, air quality control, and various industrial processes where the movement of air plays a significant role.
