Pipe Networks in watdis - Inserting node in a section of pipe

In the following youtube video can be seen as intermediate nodes can be inserted in an existing section of the pipe.
This is an important facility for the GUI, which does not exist in EPANET, and that helps a lot on agility while entering data, otherwise (as in EPANET), you have to delete the existing pipe and put the new two pipe sections. Using this option does not lose the properties assigned to the pipe.

Work of pumps in parallel and series

One of the most used element in any hydraulic system are water pumping stations. It is quite common find water distribution systems designs, where the conduct of water takes place through  pumping. That's why we have thought this component of the software to be flexible, that we cut put together, different number of pumps, in serial or parallel.

In Watdis, the characteristics of centrifugal pumps by independent elements in the catalog are introduced. Then we can construct the pumping station element, and may put pumps at a station with different head - flow characteristic curves. The following video shows how to assemble the pump station element

Example of calculating the flow in a conduit by gravity

Formulate as example a problem to determine the flow that can be conducted by gravity from a reservoir to a tank, in a ductile pipe, with loss coefficient of 130 (Hazen-Williams) and a diameter of 20 inches (500 mm). The water level in the reservoir would be 45 meters and the height of the tank where the water is delivered is 25 meters. Total pipe length is 10 km

A video example of a solution using watdis follows.
