			== Maximum pipeline flow formula incorrect for 201 pipes? ==

			Hi [[User:Sp55aa\|Sp55aa]] and everyone else,

			This section is about the formula that should be at the end of the section [[Fluid_system#Pipelines]]. There is also a discussion about the formula at the section [[User_talk:Sp55aa#Fluid_system_throughput_formula]].

			Having a formula for the maximum flow of a pipeline is wonderful. Thanks for the work you put into this, [[User:Sp55aa\|Sp55aa]].

			=== The issue ===
			I was checking the formula against the table, and I think I may have noticed that the formula doesn't agree with the table for 201 pipes. It might be relevant for me to mention that I was the one who added the 201 pipes row.

			For 201 pipes, I found that the formula produces 1000 units/second, while the table has 999 units/seconds.

			=== Possible proof of issue ===
			To make sure that I wasn't in error, I decided to see what Factorio's GUI shows for 201 pipes. Following should be two things: a picture of a screen capture of Factorio with the setup of what I did to learn about 201 pipes, and an encoded blueprint string of the setup:

			The following two pictures should show that Factorio's GUI shows the "Pumping speed" for both the input and output pumps to be 999 units/second.

			{\| class="mw-collapsed mw-collapsible wikitable" style="width:auto; border:1px solid; border-collapse:collapse; word-break:break-all;"

			! output pump picture
			\|-
			\| [[File:Output pump from 201 pipes (utc 2022-07-25 20.32.08).png]]
			\|}

			Besides only the 201 pipes row, the formula approximately agrees with every row of the table. This should be shown by the following picture of a spreadsheet:

			{\| class="mw-collapsed mw-collapsible wikitable" style="width:auto; border:1px solid; border-collapse:collapse; word-break:break-all;"
			! formula vs table spreadsheet picture
			\|-
			\| [[File:Formula does not agree with table for 201 pipes (utc 2022-07-25 20.19.27).png]]
			\|}

			If one were to always take the floor of what the formula produces, than the table and formula agree everywhere except for 201 pipes, unless I made some mistake.

			However, of course, there could be other situations where the formula and Factorio don't agree. And this could be the case for the table as well.

			=== How to proceed? ===
			If I'm not wrong in what I've noticed, then I think it's fair to ask: How should we proceed?

			One option, perhaps, is to move the formula into some work-in-progress part of the wiki.

			Another option is to add some caveat-like text to the formula on the page.

			And I guess another option is to update the formula to take into account this possible disagreement, or even possibly remove the formula altogether.

			And it might be useful to mention that it seems this formula also exists in the second [[Fluid_system/zh#.E8.BF.90.E8.BE.93.E7.AE.A1.E7.BA.BF]].

Khaim: Created page with "The category in Factorio that includes "water" and "oil" is best called '''Fluid''', not "liquid". The words "liquid" and "gas" specifically describe types of matter: solid or..."

Created page with "The category in Factorio that includes "water" and "oil" is best called '''Fluid''', not "liquid". The words "liquid" and "gas" specifically describe types of matter: solid or..."

New page

The category in Factorio that includes "water" and "oil" is best called '''Fluid''', not "liquid". The words "liquid" and "gas" specifically describe types of matter: solid or liquid or gas (or plasma; see [http://en.wikipedia.org/wiki/State_of_matter#The_four_fundamental_states Wikipedia]). "Fluid" is often used to mean "liquid", but technically is not the same type. It is anything that ''flows'', and can be either a liquid or a gas.

I would rename the page, but there are a lot of subpages and language pages that use '''Liquid'''. I don't want to break everything.
