== Pipelines and Fluid Buffers ==
A perfect horizontal [[Pipeline]] requires 1.3 meters of head lift to be filled regardless of its length. As it fills up, it also stores its own head lift proportionally, up to 1.3 meters. This effect will then propagate to the next pipeline and cause the successive pipelines to be filled up. A not completely filled pipe segment has a head lift of 1.3 meters. Fully saturated pipes can propagate more than that (be it from a pump or other buildings). Fluids take time to fill up a very long pipe, but once it is fully filled, fluids in it can flow with the maximum flow rate (or whatever the source's flow rate is).

A vertical pipeline can store maximum head lift equal to its vertical length, measured from its bottom end to the top end. Its stored head lift is proportional to the percentage of the fluid in it; for instance, a half-filled 10-meter pipeline stores five meters of head lift. A vertical pipeline needs to be fully filled before the next pipeline above it can start to receive fluid. A very tall pipe requires a very high head lift to be filled. If a lower head lift is provided, it can only be filled partially.

If somehow the fluid source is stopped and the source's head lift drops, the previously stored head lift in pipes will attempt to equalize among connected pipelines; this means fluids can backflow from the pipes with higher head lift to the pipes with lower head lift, as pipelines are bi-directional in nature. For example, if there are two horizontal pipelines with identical length connected in series, with one of them filled and the other one emptied, then the fluid within them will equalize themselves until both are filled equally, that is, 50% full. During this equalization process, the fluid flow can oscillate back and forth, taking a long time before it fully stabilizes.

All of the above principles also hold for [[Fluid Buffer]]s and [[Industrial Fluid Buffer]]s – they are just Pipelines but with much larger capacity and head lift. Note that their stored head lift is counted from the pipe inlet level, not from the Foundation level. Combining all the above knowledge, chaining multiple Fluid Buffers in series is a bad idea as the system requires a very long start-up time – consider attaching buffers to the 'sideways' of a Pipeline instead, by using [[Junction]]s.
