Gooseneck Properties

Property Name Description
Air Flow Rate Positive <numeric value>
  • Sets a value for the amount of flow through gooseneck.

    Used to calculate overall flow rate during analysis operations.

This property is used by the Analysis tool for calculating upstream air flow rates for connected elements.
Angle <angle value> between 90° and 180°
  • Sets the angle the spout curvature covers.
Connection | End Type fl -<numeric value>
  • Sets and sizes end with a flange connection.
m -<numeric value>
  • Sets and sizes end with a male connection.
fe -<numeric value>
  • Sets and sizes end with a female connection.
Separate End Type entries for each End Spec with a semi colon.

Example: fl-2;fe-.13 creates a flange at End1 with size 2, and a female connection at End2 with an overall reduction of component's dimensions of .13

Connection 3 | Length (L3) Positive <numeric value>
  • Sets the length at gooseneck base that adds an offset to mount it on a roof curb.
Enabled when Cowl Setting property is set to 1-No Cowl.
Cowl Depth

Cowl Length

Cowl Width
Positive <numeric value>
  • Sets the Depth, length and Width of the cowl, respectively.
Enabled when Cowl Setting property is set to 2-With Cowl.
Cowl Setting
  • 1-No Cowl - without cowl assembly at base.
  • 2-With Cowl - cowl attached at the base end to prevent back flow.
  • Sets or no Cowl to the Gooseneck.
Gooseneck without cowl enables L3 property.
Radius Positive <numeric value>
  • Sets the radius of the curvature formed by the gooseneck.
Transition1 Length,

Transition2 Length

Sets the transition length. Transitions coupled at base end and along the upstream at tip respectively.
