Always check local regulations before design. Capture velocity - v1 - for an exhaust hood can be estimated with the empirical equation. v1 = q / 2 y2 c (1) where. v1 = capturing velocity (m/s) q = air volume flow (m3/s) y = distance between table and exhaust hood (m) c = circumference of the hood (m) (1) can be modified to calculate air volume ...

The velocity distribution in the suction area of an unrestricted round duct is similar, with an "effective suction diameter" D e =0.81D and a maximum velocity V m ≈1.1v 0. The size of these wakes and the velocity uniformity level depend on the hood design and the airflow pattern in close proximity to the hood …

1. Vacuum pressure or suction is measured in inches of water gauge, w.g. and is the basis of a properly functioning dust collection system. 2. The system fan must supply enough suction to pull the materials from the collection point(s) all the way through the ductwork to the baghouse and then through the filters and out to exhaust. 3.

Lengths of Hoods • Capture at the source • Try to encompass area where dust is being generated without interfering with the operation. Three important factors when designing a hood. 1. Shape of the Hood. It must be shaped to allow material to travel in a straight line to hood outlet without suction. Otherwise, angle of deflection is critical.

contaminants. Good hood design will create air flow past the source of contamination sufficient to remove the contaminated air around the source and to draw that air into the hood. A. 1.3 PROCESS DESIGN OPTIONS: A complete enclosure will be the most efficient from an exhaust standpoint, but may be unrealistic from an operations point of view.

exhaust hood. Flow toward the suction opening must be sufficiently high to maintain the necessary capture velocity and to overcome opposing air currents. Elimination of sources of air motion as a first step in hood design is an important factor in cutting down the required air volume and the corresponding power consumption.
