Epanet for ipad and iphone

info@transparent-blue.com (Administrator) — Wed, 17 Jul 2013 18:46:32 +0000

If you have an iphone or ipad tablet, you can take EPANET on your mobile device. The app is available at the Apple store at the following link:Epanet for iphone and ipad tablet

In this version you can load the EPANET file (from an email or passing with itunes) execute it, and display the results of calculation of the hydraulic network.

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

info@transparent-blue.com (Administrator) — Mon, 08 Apr 2013 20:35:26 +0000

In the following youtube video can be seen as intermediate nodes can be inserted in an existing section of the pipe. {youtube}j1Sxr98dpFY{/youtube} 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.

We've got new ios and android apps in itunes and google play. The links follow

Hydraulic engineering apps for iphones and ipad

Android Civil and mechanical engineering apps

Among the apps are one for calculating head losses in piping, including calculation in fittings and valves, another for calculation of pumping total dynamic head and other for determining diameter and slope of a section of sewer.

Example of calculating the flow in a conduit by gravity

info@transparent-blue.com (Administrator) — Mon, 12 Apr 2010 01:07:28 +0000

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.

Work of pumps in parallel and series

info@transparent-blue.com (Administrator) — Fri, 09 Apr 2010 00:00:00 +0000

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

Pipe bends without placing intermediate nodes

info@transparent-blue.com (Administrator) — Mon, 22 Mar 2010 18:07:09 +0000

Here we will refer to one of the advantages relating to the graphical interface be able to make bends in tracings of the pipes.

In watdis polyline curves can be drawn between two nodes of a stretch. The polyline is transformed into a single pipe whose initial node matches the first end of the polyline and the end node coincides with the termination of the polyline. Here in red an example of a polyline between nodes C4 and C5. The inflections of the polylines are done with a simple right click of the mouse..

This simplifies the model, since in the inflections there is no need to place additional nodes, as in epanet for example. So if you put a background image with the streets, and some of the streets are curved, in watdis you can trace the lines with inflection points without placing nodes, and nodes placing is only required in the corners of intersection or nodes where demand exists. The length is calculated as the total length of the polyline.

Recent changes in the graphical interface of watdis

info@transparent-blue.com (Administrator) — Wed, 24 Feb 2010 14:20:25 +0000

We have worked on several improvements to the graphical interface of watdis. Among them we can mention the following:

1. That at the pan and zoom the display network does not change the default size of the nodes.

2. Now You can change in a panel the default display size of the network nodes.

3. The node type of a network can be changed with a single click of a mouse.

These new features can be seen in the video below.
