# Boundaries | Sprinklers

FluidFlow contains a database of sprinklers which can be used when building a network. The user can also very easily add new sprinkler models to the database for specific modelling applications. Note, you only need to add a component to the database once. It will then be stored for all future projects. To access this database, select the Database | Boundaries menu item:
Actions
Add | Add a new sprinkler to the database.
Delete | Delete the currently selected sprinkler record from the database.
Clone | Makes a copy of the currently selected sprinkler record and adds it to the database. For example: cloning '11Y T1' will result in a new record '11Y T1 (2)'. Note: This action is only available via the context menu when you right-mouse click on the current record.
Import | Import sprinkler records from a FluidFlow2 database.
Load | Loads a ".comp" file - containing a sprinkler record - and adds it to your current database. See 'Save' below for more information.
Save | Saves the currently selected sprinkler record as a ".comp" file type. This means that if you have created a new sprinkler in your local database (stored on your "DATA" Folder), you can save the sprinkler file and share with another user. The user can then use the "Load" button to select the file and add the new sprinkler data to their local database.
Sprinkler Data Entry
Name | Allows you to enter a descriptive name for this element.
Manufacturer | The name of the sprinkler manufacturer can be entered here.
Materials | The materials used to manufacture the sprinkler may be defined in this field, e.g., Steel, Stainless Steel, Bronze, etc.
Applications | The specific applications in which the sprinkler may be used, e.g., Chemical, Power, etc.
Nominal Size | The Nominal Size of the sprinkler refers to the connection size.
Size Unit | This refers to the diameter/size units used in the above entry.
Min Operating Pressure | If there is a minimum pressure rating for the sprinkler, you should enter this value here. Leaving the value at 0 means that FluidFlow will not complete an operating pressure check.
Max Operating Pressure | If there is a maximum pressure rating for the sprinkler, you should enter this value here. Leaving the value at 0 means that FluidFlow will not make an overpressure check.
Operating Pressure Unit | The pressure units used when defining the Min & Max Operating Pressures.
Defined By | There are two possible entries for this field: 1) Table and 2) Nominal K. If we select "Table", a new data-entry field titled "Curve Fit" will appear where we can define the performance data
Curve Fit | This is where we define the performance data for the sprinkler. Simply fill out the columns for flow and associated pressure loss and FluidFlow will automatically develop the curve plot. Figure 2 gives an example curve fit relationship for sprinkler model "Full Cone 1" 1/4". Note, you can select the most appropriate Curve Fit Type and Equation Order for your data.

Curve Fit Data Entry
Curve Fit Type | There is only one selection available: Polynomial.
Equation Order | There are several options available: ▪BestFit ▪Linear ▪Quadratic ▪Cubic ▪Quartic ▪Quintic
Flow Unit | The flow units used when defining the flow rate coordinate for the sprinkler.
Pressure Loss Unit | The units used when defining the Pressure Loss coordinate for the sprinkler.
