Typically, jet diffusers are an option for locations the place linear slot diffusers, double deflection diffusers and other types of diffusers are not possible.
The horizontal strains are for quantity flow rate. The downward diagonal lines are for velocity, the upward diagonal traces are for duct diameter.
For this reason, you’ll do the recording, find the styles and tell your helper the amount the damper has to be closed. Understand that the airflow measurement work is exhausting. So, attempt to not talk to your helper to close and open up the exact same damper far too routinely.
