What process involves measuring duct's velocity pressure at equal points?

When measuring duct's velocity pressure at equal points, traversing the duct is the correct process. This method involves taking multiple measurements of velocity pressure at specific points across the cross-section of the duct. By systematically measuring at equal intervals, it allows for a comprehensive understanding of the airflow characteristics within the duct.

The data collected during traversing can then be used to calculate the average velocity of air traveling through the duct, which is crucial for ensuring proper system performance, balancing the air distribution, and identifying any potential issues such as airflow restrictions or leaks.

While calculating airflow and taking average velocity also relate to understanding air movement in ducts, they are outcomes of the traversing process rather than direct measurements. Measuring static pressure involves a different approach, focusing on air pressure in the duct without the velocity component. Overall, traversing provides the needed method to capture the dynamic nature of airflow across the duct system.
