Problem

How can I view the Darcy-Weisbach Friction Factor (f) for my pipes? Only the Roughness Height input value is shown.

Solution

As of version 10.02.02.6, the Darcy-Weisbach Friction Factor (f) is an intermediate calculation and is not part of the set of results that can be viewed in the user interface. The following article details the process in used to calculate headloss using the Darcy-Weisbach method: Darcy-Weisbach Headloss Calculations in Steady State and EPS

Enhancement #1058078 will be considered by Bentley Product Management for a future release (for example to display the 'f' as a result property). In the meantime, consider the following:
