Factors Influencing Face Velocity for Fume Hood Containment

Although there is a growing consensusthat face velocity cannot be applied as a sole evaluation indicator of fumehood containment performance, face velocity measurement is still of importancein hood performance evaluation because of its convenience and simplicity. Thework reported in this article aims to understand the impact of variousinfluential factors on the robustness of face velocity for fume hoodperformance evaluation through comprehensive field tests.
