Solids Builder - EPANET Links - Pipe

The pipes lead the water from one point to another in the network. EPANET assumes that all pipes are full at all times. The direction of flow is from end at the highest head (internal energy per weight of water) to the bottom head.

When you want to define a device as a Pipe, you must add the tool Pipe to the Constructor:

When adding the tool Pipe, fill in your properties, in the tool's properties frame:

In the Constructor, the following properties must be filled in:

• Identification
  • Name - name of the activity
    The point name must follow the naming rules
  • Description - when the name of the activity is not enough to give context to the activity, use the description field
• Head Loss
  • Loss Coefficient - Minor unitless loss coefficient that applies when the valve is fully open
    Minor losses caused by bends and connections can also be accounted for by assigning the pipe a lower loss coefficient.
• Pipe
  • Diameter - Diameter of the pipe, mandatory property, assigned by the Constructor (see below)
  • Initial State - Determines if the pipe is initially
    • open
    • closed
    • check valve
• Reactions
  • Wall Coefficient - Coefficient of reaction of the wall to the pipe. Use a positive value for growth and a negative value for decay
  • Mass Coefficient - Mass reaction coefficient for the pipe. Use a positive value for growth and a negative value for decay

In the image, the Diameter property of the pipe is given by a property modeled in the properties frame:
