Animation & Explanation by BIGS
Currently no longer available as an animation, but accessible here as a YouTube video in English, free of charge. Click on the image to start the video.
As a free animation, however, it is available here as a downloadable executable file for Windows Strömung-im-Rohr..exe.zip
Please note that some Windows settings may block the download. However, under the „More Information“ button and then the „Run Anyway“ button, you can allow the download.
Explanation of the Animation and the Topic „Flow in a Pipe“
- A1 – the cross-sectional area of flow on the left side
- v1 – the corresponding flow velocity
- A2 – the cross-sectional area of flow in the middle
- v2 – the corresponding flow velocity in the middle section
- V = A * v * dt – represents the volume of fluid passing through
The animation shows a streamtube where no fluid particles escape through its boundary.
On one side, the volume A1 * v1 * dt enters the streamtube, and on the other side, the volume A2 * v2 * dt exits. Since the fluid is assumed to be an incompressible medium, both volumes must be equal. Thus, the continuity equation applies:
A1 * v1 = A2 * v2
