The program calculates the steady state of an aqueduct.
It analizes the performance of the system and can be used to design system components to meet distribution
In addition performs water quality modeling, calculating the source tracking and determining the staying time of the water.
The network is described by a
directed graph in which:
- arcs are the elements of the
- nodes are the points of
junction of two or more elements.
:Possible elements are:
(feeds to the net),
- demands (concentraded in the
nodes or distributed along the pipes),
- head pumps,
- pressure relief valves,
- interception valves,
- minor losses
(pipe enlargements, pipe constrictions, bends, tee joints, .... ).

others are inserted only for completeness:
- Darcy' formula,
- Bazin's formula.
The more are the families supplied,
the less is probable that all flow rates have the maximum value at the
defined as the ratio between maximum
and real demand;
where maximum theoretical
demand is the product of family maximum demand by the number of supplied
coefficient changes along the network.
To design correctly an aqueduct it is necessary to apply the contemporaneity coefficient to every pipe
flow rate, according to the number of families supplied by the pipe.
