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 in
accordance with the Industrial Ventilation Manual. (See
Appendix E) 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. A total of four
readings will be taken for the 2' enclosure, six readings
taken for the 3' enclosure and eight readings taken for the 4'
enclosure and then averaged.
