Circular
Multicone Diffusers (CMD) - Horizontal |
| To select a diffuser for a given volume of air.
Project a line from the airflow rate line through a point on the radial throw line to
intersect the diffuser size required. Total pressure, jet velocity and neck velocity can be determined at the relevant points of intersection. Sound power levels can be determined by projecting across horizontally from the point of intersection with the neck velocity scale. |
