# Pipe Roughness

FluidFlow contains extensive information on roughness data for each type of pipe material ranging from "Clean and New" to "Heavily Corroded". This data can be used when modelling piping systems or, alternatively, you may choose to enter your own specific values based on available pipe material knowledge. Figure 1 provides an overview of the database of pipe roughness categories which can be accessed by selecting the Database | Pipe Roughness menu item. Figure 1: Pipe Roughness Database.
Actions
Add | Add a new roughness entry (for the selected Material) to the database.
Delete | Delete the currently selected roughness record from the database. Note: There are certain records, added by Flite, that you will not be able to delete.
Data Entry
Description | Descriptive name for the roughness value.
Absolute Roughness | Value for the roughness of the inside surface of the pipe wall. This absolute roughness value is used to determine the pipe relative roughness when performing pipe pressure loss calculations.
Roughness Unit | Refers to the units used to specify the roughness value.
