Duct Pressure Drop Report Label Display and Order Dialog Box​

See the Common Label and Schedule Information section for more information about using the and buttons and the Key ☰, Label, Width, Justification ▾, and ☐ Display fields.

Values in the Key ☰ column are listed alphabetically below.

  •  Airflow Volume The volume of air flowing through the duct section.

  •  Duct ID The label and number identifying the duct. The ID is matched to a label on the drawing. Use the Pressure Drop Report Duct ID Block option in the Miscellaneous options section to set the block used for the duct ID.

  •  Duct Length The length of the duct section.

  •  Fitting C-Value The c-value used to calculate the pressure drop through the previous fitting.

  •  Fitting Table The fitting table used to calculate the c-value for the fitting. The fitting tables used are a combination of tables taken from ASHRAE and SMACNA.

  •  Pressure Drop in Section The pressure drop through the straight run of ductwork.

  •  Pressure Drop in Fitting The pressure drop through the fitting previous to the duct section. Equal to the c-value times the velocity pressure.

  •  Static Pressure at End of Duct The static pressure at the end of the duct section.

  •  Static Pressure at Start of Duct The static pressure at the start of the duct section.

  •  Total Pressure at End of Duct The total pressure at the end of the duct section.

  •  Total Pressure at Start of Duct The total pressure at the start of the duct section.

  •  Velocity The air velocity in the duct section.

  •  Velocity Pressure The velocity pressure in the duct section.
