Feature	Description
Symbol	Fitting type symbol.
Type	Fitting type short code.
Nominal	Nominal Fitting size.
K Method	The method by which the K value is determined.
K Value	Local loss coefficient of Fitting (‘Calculated’ for Hooper 2K, Darby 3K, Expansion K and Contraction K methods).
K1 Value	K1 coefficient of Fitting (Applicable for Hooper 2K and Darby 3K).
K∞ Value	K∞ coefficient of Fitting (Applicable for Hooper 2K).
Kd inch 0.3 Value	Kd coefficient of Fitting (Applicable for Darby 3K).
Description	Fitting description.
Qty	Quantity of Fittings on the Pipe.
Position	Fitting position on the Pipe. Define to be at Start or End of Pipe.
Save	Save the Fitting selections to the Pipe currently selected in the drawing pane.
Clear	Clear the Fitting selections.
Cancel	Close the Pipe Data screen without making any changes.
Pipe Size	Click to display Fittings to match the current Pipe size (Applicable for Standard K).
Pipe Sizes	Dropdown list of pipe sizes, click to display matching Fitting sizes. (Applicable for Standard K). For Hooper 2K, the diameter of the currently selected Pipe is displayed. For Darby 3K the nominal size of the currently selected Pipe is displayed. For Expansion K and Contraction K, the diameter of the currently selected Pipe (D1) and the diameter of the follow-on (D2) is displayed. If there is none or more than one follow-on Pipe, then D2 will be displayed as Invalid.
Fitting K Method	Dropdown list of Fitting K methods. Select the type of Fitting K methods to be displayed in the database.
Fitting Database	Listing of Fittings and friction coefficients and/or constants.
Transfer Selected (Start)	Transfer the selected Fitting data from the database to the start of the currently selected Pipe. (Applicable for Standard K, Hooper 2K, Darby 3K). Expansion K and Contraction K Fittings can only be placed at the end of a Pipe.
Transfer Selected (End)	Transfer the selected Fitting data from the database to the end of the currently selected Pipe.
Standard Fittings Calculate K value for	Calculate local loss coefficient for: entrance rounded, gradual enlargement, gradual contraction, sudden enlargement, sudden contraction or long pipe bend.
Create Fitting	Create data for custom Standard K, Hooper 2K or Darby 3K Fittings.
Remove Fitting	Remove data from Fittings database.
