linear devices

Constructor in 
Pressure Networks.
Links direct the flow from one EPANET node to another. ON SOLID, the links are modeled in linear devices
via Constructor in Pressure Networks.
For SOLIDOS to recognize the properties of a link in linear device, it is necessary that the
Constructor contains one of the tools listed below, in order to implement such properties:
Note the penultimate item. It is he who will define the device as a conduit for EPANET. Also note that the conduit properties that depend on the geometry/location of the device
are defined in the properties of the 
Conduit Activity:
Link types include:
Pipes - The pipes lead the water from one point to another in the network
Pump - links used to raise water to higher altitudes
Valves - Valves are used to control pressure or flow at a specific point in the network
