Introducing the components of a simulated network

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.

In info works. WS pro

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.
