Problem description

I want to add pressure drop on Diffusers in Duct System Sizing tool, but I don’t see this option. How is that possible?

Solution

In Duct System Sizing tool, you can change the Airflow, but to change the pressure, you must do so from the Placement Window (Modify element). You can find it in the Diffuser Parameters tab.
