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.
