Manifold

Manifold, a.k.a. in-line splitting / merging refers to a type building style where splitters or mergers are aligned in a straight line, usually parallel to the arrangement of buildings. This allows for compact building space and easier expansion.

It is the opposite fill method to the balancer.

Conveyor Belt manifold

 * Due to the the mechanisms of Splitters, the machines closer to the source will fill up faster and start running, the machines at the end of the line will have to wait for the resource to fill up the preceding machines first before receiving their input resource.
 * If one output of a splitter is saturated with items, all of the remaining items will automatically overflow to the remaining connected outputs.
 * Same applies to outputs. The output from the nearest machine will be used first. If the output belt is saturated, the last machine can take a long time to be emptied.
 * Given enough time, all machines in the manifold will be running at 100%, providing the input and output items rates are sufficient and the item speed is not limited by the conveyor throughput.
 * If the conveyor throughput is a limiting factor, consider using an 'injected manifold', where supplementary supply belt/s are merged somewhere in the middle.

Pipe header
A pipeline manifold, a.k.a pipe header, is a kind of arrangement where a 'main' pipe is connected to a series of secondary pipes. It can serve either as a fluid distributor or a fluid collector. This can be constructed by chaining a series of Pipeline Junction Crosses connected with Pipelines.

A pipe header works with the following principles:
 * The total fluid input must be equal to the total fluid output (conservation of fluid flow).
 * No single segment of pipeline can exceed the flow rate of 300 (Mk.1) or 600  (Mk.2).
 * Pipelines are bi-directional, so any fluctuation in fluid amount or flow rate will be auto-balanced by themselves. That means you won't have to worry about the fluid direction in individual pipe segment, only need to consider the overall flow.
