To determine the actual face velocity at the sash opening, airflow velocity readings
will need to be taken. This should be done across the sash opening of the
enclosure. The “average face velocity” is achieved by taking readings in two rows
across the enclosure with the readings 6" from the ends and evenly spaced every
12"; the first row is 3" down from the upper sash foil and the second row is 3" up
from the work surface.
