Tutorial
Length:
2 min.

00:04
All simulated water networks are comprised of two components.
00:08
Nodes sometimes referred to as points and links.
00:13
A node is a location within the water supply
00:15
system where head inflow or outflow is known.
00:19
A link is a connection between two nodes.
00:23
It is important to understand how nodes and
00:25
links function in a simulated network model.
00:28
In info works. WS pro
00:32
to run successfully. A network model needs a source of pressure or head
00:37
nodes are used to represent sources of pressure head.
00:42
These types of nodes can be a fixed head such as a well or a reservoir
00:48
notes also can be assigned demand to account for customer usage and or leakage.
00:54
A note is also a point of the network with a known location and elevation.
00:60
Some nodes in a network represent real network components like fire hydrants.
01:05
Other nodes are virtual and only exist for purposes of simulation
01:10
energy or pressure may be added or removed entirely between these points
01:15
because nodes like these can be fictitious.
01:18
You can think of nodes as joining links as links tend to be actual objects
01:23
to be clear links, transfer water flow from one node to another.
01:29
Links are most often pipes but they may be pumping stationss, meters or valves
01:35
because flow and pressure changes between their inlets and outlets.
01:38
Valves and pumps are considered to be links in info works. WS pro
01:44
pumping stations add energy to the water flowing through them and
01:47
valves control the flow of water by changing its hydraulic energy.
01:52
The shape of a link in ground elevation at any point
01:55
along the link is not considered in the hydraulic simulation.
01:59
The most important factors to consider are the
02:01
length diameter and friction coefficient of a link.
