Details on Edit Duct Sections

Information on the Edit duct section dialog in duct network calculation.

You are here:

Project tab ➤ Ventilation discipline ➤ Analyse tab ➤ Calculation ➤ Edit duct section...

Geometry

Change the duct length, the cross section shape or maximum dimensions of the duct.

Calculation presettings

Enter an additional pressure loss, a maximum velocity or a maximum pipe friction pressure loss for the duct section.

By specifying an additional pressure loss you can take into account pressure losses from components and fittings which are not part of the model. The additional pressure loss is added to the pressure loss from zeta (Z) of the relevant duct section.

Sound level

Displays the octave bands of the current sound level at the exit of this duct section in the direction of the air diffuser or protective grating.

Duct material and Insulation

Displays the duct material and insulation materials, if assigned.
