Question: 1 / 400

How can you check for airflow in a system in a simple way?

Using an anemometer

Using a psychrometer

Seeing if you can hear the airflow

Seeing if you can feel the airflow at a distance of about 2 to 3 ft from each register

Checking for airflow by feeling it at a distance of about 2 to 3 feet from each register is a simple and practical method. By sensing the airflow, you can quickly determine if the system is functioning correctly and if there are any significant issues with airflow distribution. This method allows for a basic assessment of airflow without the need for specialized equipment or tools.

Options A and B involve using specific devices - an anemometer and a psychrometer, respectively - which are more advanced tools used for precise measurements and airflow analysis beyond a basic check. Option C, hearing airflow, may not always be reliable or provide a clear indication of the system's performance compared to physically feeling the airflow from a distance.
