Issue description
In the game, sometimes it is necessary to use a pipeline to mix and transport liquids（Such as chemical fertilizers and organic fertilizers）, but in the current code implementation of the pipeline, one liquid must be drained before another liquid can be injected. Therefore, when the pipeline is relatively long, it takes more time to empty the pipeline and, making the long pipeline very inefficient when transporting mixed liquids.
Reproduction steps
The two liquid tanks above are very inefficient at emptying, and looking at the longer pipes, you can see that you have to wait for one liquid to drain before transferring the next.
