Describe how pressure waves are generated and propagated in a distribution system.
Transcript

When using InfoSurge, it is important to understand how pressure waves begin and how they travel through a water network.
00:11
Wave method analysis is the study of how waves are generated
00:15
and how they interact with other parts of a water network as they propagate.
00:20
The wave characteristic method (WCM), which is the computational technique for transient flow analysis used by InfoSurge,
00:30
is based on the concept of pressure wave generation and propagation in pipe systems.
00:36
Many variables determine the characteristics of a wave, including pipe friction.
00:41
Wave speed is predominantly based on pipe properties, including material, diameter, and wall thickness.
00:49
When a wave reaches a boundary, such as a junction, the wave reflects and propagates to other parts of the network.
00:57
Pressure waves originate from the source of a disturbance.
01:01
A disturbance could include: The partial or full closing or opening of a valve
01:07
Starting or shutting down a pump
01:10
A pipe rupture
01:12
A change in reservoir pressure
01:14
Closing a check valve
01:17
Opening a pressure relief valve
01:20
Pressure waves are modified by system discontinuities, such as:
01:25
Components with head/flow characteristics, like valves and pumps
01:31
Junctions
01:32
Surge control components which inject or remove liquid
01:37
InfoSurge has built-in pipe wave speed calculators.
