Do you know how to calculate the Water Hammer?
Perform the Basic Analysis with our Simple Water Hammer Software
Our idea with ARIETE is to offer a basic and sufficient computer tool so that the majority of the civil engineers can perform the pipeline’s basic water hammer analyses, without having to resort to more sophisticated and expensive software of which, for sure, they will only use about 50 % of its characteristics.

Why ARIETE must be among your hydraulic pipeline analysis tools?
Water Pipeline Design and Analysis involves not only the basic hydraulic designing but also the determination of pressure heads and flows conveyed by the system under different operational conditions, aimed at determining the capacity of the pipeline’s components to withstand the calculated internal pressures in the system.
Our ARIETE Water Hammer Software has been created with the intention of presenting, as explicitly as possible, the calculation results in the form of a Pipeline’s Longitudinal profile chart and plotting on it the resulting hydraulic grade envelopes in the system for different operating conditions, which range from values resulting in steady state conditions to those obtained under conditions of unsteady flow regime.
Using ARIETE for water hammer calculation is aimed at studying what the surge pressures generated in the water pipeline system under specific situations are, for example, in a sudden failure of pump equipment and the opening and closing of control valves. It is then possible to evaluate the effect that water hammer control devices, such as Water Surge Tanks, Air Chambers, Bypass lines, and surge relief valves, among others, would have on the system’s hydraulic response.
In summary, Ariete is a computational tool that allows the evaluation of different analysis scenarios and, in turn, allows the visual comparison of results for such scenarios so that the civil engineer can achieve better water pipeline designs.
Ariete’s main window shows the pipeline’s longitudinal profile, plotting the calculated and allowable hydraulic grade envelopes:
You can compare hydraulic grade envelopes for different analysis scenarios:
In the Pipeline Data dialog, the geometrical and water hammer calculation parameters will be entered:
You can create libraries of Centrifugal Pumps with different characteristics curves:
You can include water hammer control devices at the pumping stations’ discharge pipe:
Along the pipeline’s length, it is possible insert water hammer control devices, such as two way surge tanks, among others:
You can visualize the water hammer calculation results in charts, which you can easily configure to enhance their presentation:
You will be able to generate multiple data series charts in order to compare the selected scenario results:

Frequently Asked Questions
In Simple Terms: What is Ariete used for?
The main function sought with Ariete is to verify the design of water pipeline systems under internal pressures conditions.
That is why its main interface presents the analyzed pipeline longitudinal profile, including the envelopes of maximum hydraulic grades that piping components can withstand based on its nominal pressure. Thus, the user will be able to visually determine, via comparing the resulting envelopes, which pipeline’s sections are at risk of failure when the water hammer phenomena takes place.
If you want to see how Ariete allows you to easily detect those pipeline sections that won’t withstand the calculated internal pressures, check out this Tutorial.
What Water Hammer Control Devices does Ariete actually include?
In Ariete’s actual version, it is possible to include the following water hammer control devices:
- One Way Surge Tank
- Two Way Surge Tank
- Surge Relief Valve
- Air Chamber
When the modeled system is a pumping pipeline, it is possible to include at the pumping station’s discharge pipe, the following water hammer control devices:
- Air Chamber
- Surge Relief Valve
- Pumping station’s bypass line.
- Flywheel (pumping equipment’s rotational inertia increasing)

What so complicated is the Pipeline System’s Data Introduction in Ariete?
Our target with Ariete (as well as with our other products in general) is to put within the reach of civil engineers and professionals in the hydraulic area, designing tools that allow them to perform, in a quick and reliable form, the process of designing and making decisions about the need for more complexes calculations (or software).
Bearing in mind the previous idea, is that we seek to make the data introduction as practical as possible, so that the complexity is negligible, considering the type of phenomenon that can be analyzed with Ariete (hydraulic transients, water hammer).
Specifically, in the case of the data required to perform the water hammer calculation in pipelines, you just need to enter the pipe material, wall thickness, and the number of control points in which the pipeline will be divided. Leave the rest to Ariete.
In this Tutorial, you’ll see how easy is to configure the pipeline data to be ready for water hammer calculation with Ariete.
What kind of Water Conveyance Systems can I model with Ariete?
Ariete is oriented to the Design and Evaluation of simple pipeline systems, either operating by gravity or by pumping (gravity or pumping mains). These types of systems have a water source installation at their upstream end (pumping station, reservoir or tank), a main pressurized conveyance pipe, and a receiving water installation (reservoir, tank or valve).
A pipeline system in Ariete can be of any length, but it is only possible, in the current version, to specify a unique pipe’s diameter and material, and that’s why it does not include special fittings on the line such as tees, wyes, etc.
On which method for a Pipeline’s Water Hammer Calculation is Ariete based?
Ariete is based on the well-known Method of Characteristics.
How do I learn to use it?
