We’re excited to announce a powerful enhancement to the FlowWorks Graphing Tool: the Pipe Diagram feature. This new functionality provides users with greater visual context when analyzing flow and velocity data in their collection systems.
What Is the Pipe Diagram Feature?
The Pipe Diagram allows users to overlay pipe size visuals directly onto graphs. This makes it easier to interpret how flow and velocity data relate to infrastructure size — ideal for identifying capacity issues, surcharging, and supporting Infiltration & Inflow (I&I) investigations.
Graph Setup Overview
To use the Pipe Diagram feature, we will take a 3-step approach which we will be reviewing further in this support article:
-
Setup your Graph options
(Depth on the Y-axis / Velocity on the X-axis. Set Graph Type to Scatter) -
Access the Pipe Diagram tool
-
Set your Pipe Diagram options including Pipe Diameter
Optional: apply a Curve Fit using Manning’s equation along with the Pipe Diagram. For more on curve fits, see the support article here
Let's review the 3-step process below!
1. Setup your Graph
-
Open the Graphing Tool in FlowWorks
-
Select your site > Channel(s) (e.g., flow, velocity), and date range
-
Set the Graph Type to Scatter Plot (this is required to enable the Pipe Diagram)
-
Click Plot Data
2. Access the Pipe Diagram
Once your scatter plot is generated, click Tools > Pipe Diagram using the top menu above the graph.
See below image for more detail (accessing the Pipe Diagram).
3. Set Pipe Diagram Options
In the Pipe Diagram dialog, you can enable or configure the following:
-
Show Pipe Diagram
-
Show ISO FlowLines
-
Pipe Diameter (input a value and select units)
- Click OK to apply.
Note: The Pipe Diagram and ISO FlowLines are only available when depth is plotted on the Y-axis and velocity on the X-axis. graphing will automatically put a depth channel on y-axis and velocity on x-axis assuming the units are correct. This applies to both imperial and metric (inches / feet vs. millimeters / meters)
Your graph will now update to include the Pipe Diagram based on the pipe diagram options and selected channels. In the example below, both ISO FlowLines and Pipe Diagram are enabled with a pipe diameter of 0.5 meters.
You may also apply a Curve Fit using Manning’s equation for additional analysis.
