To my knowledge, it really doesn't. A bit of fluid at level Z will never, due to pressure alone, move to a level higher than Z, right? It can cause the level of fluid to rise in some distance place which looks to the user like 'pushing fluid up', but calling it that does not help demystify (har) and explain how pressure actually works.

Updates[edit]
I've done some quick tests to verify that fluid mechanics have not been changed from 40d and went ahead and pulled this page forward to 2010. However looking back over this page, I really don't like the way the content is presented here, so I may go back and rewrite this entire page to clean it up a bit when I have the time. Doctorzuber 07:01, 11 April 2010 (UTC)
- Okay, I took the time to heavily re-write this page using some elements from the old 40d page. The material is basically the same, I just added more diagrams for u-bending which I think very efficiently illustrates how pressure works in a quick and visual way. I also made some slight adjustments to the old ascii diagrams jazzing them up a bit with some unicode. I now leave this open for the wolves to descend upon and tune this page up even further. Doctorzuber 01:54, 12 April 2010 (UTC)
- Right, well I'm new to the whole wiki thing, so I wasn't confident changing it, but shouldn't the redlink "Hatches" instead go to the page "Hatch covers"? http://df.magmawiki.com/index.php/Hatch_cover --195.2.132.217
- Hatch should be correct, but apparently the redirects are screwing that up right now, I changed it to hatch_cover for now since I can't edit the redirects myself. --Doctorzuber 07:09, 4 May 2010 (UTC)
How do i build a water cannon[edit]
Hi, how do I achieve pressure? If eg. I have a reservoir that I want to pressurize, so that I can shoot it out like a water cannon.--208.81.12.34 18:32, 2 July 2010 (UTC)
- You need to create pressure. You can either fill your reservoir to many levels above your "cannon" so there is natural pressure, or you can use a pump stack to create the pressure directly since pump stacks push water quite quickly anyhow. Probably the fastest system is to have a tall multi z-level reservoir with a pump stack pulling from the bottom level of the reservoir. Be warned, this does tend to empty the reservoir VERY quickly. --Doctorzuber 01:31, 3 July 2010 (UTC)
Flow through Diagonal[edit]
Water flowing through a diagonal and then through a u-bend will only reach a level 1 z below the level the diagonal is on. Making changes to the neutralizing flow section to make it a little clearer. --Arhm 05:08, 25 July 2010 (UTC)
- I'm not certain that statement is true, I'll have to check that one. Rivers do fill to z - 1, until you place a dam. Once you've built the dam the river fills to z - 0. But you're not describing a river. I'm thinking it will fill back to z - 0 like a blocked river. --Doctorzuber 07:41, 25 July 2010 (UTC)
- I went ahead and verified this. Just one more quirky behavior of water. Not sure I agree with your wording. I find it to be a bit ambiguous, but I don't feel like editing it just now. --Doctorzuber 08:09, 25 July 2010 (UTC)
Unpressurised magma does not behave like this, though one may expect it. Unpressurised magma flowing trough a diagonal will still fill the same z-level to 7/7. Yes, it was Fun. --Ghostbird 20:17, 13 April 2011 (UTC)
A theory section perhaps ?[edit]
Explaining this diagram from this thread. --Arhm
- You're in the theory section. Discussion pages are routinely used for theories and questions. --Doctorzuber 07:33, 25 July 2010 (UTC)
Pressure Never Pushes Fluid Up[edit]
To my knowledge, it really doesn't. A bit of fluid at level Z will never, due to pressure alone, move to a level higher than Z, right? It can cause the level of fluid to rise in some distance place which looks to the user like 'pushing fluid up', but calling it that does not help demystify (har) and explain how pressure actually works. 98.255.32.212 10:25, 1 August 2010 (UTC)
River ended, is that considered a dam?[edit]
I have a map where a river ended, you know where it branches out and then stops, is this considered a dam?--96.248.39.87 14:55, 4 December 2010 (UTC)
- This is not the rivers end, it is its source area as rivers tend to end into bigger bodies of water like oceans or lakes... The area is handled like an aquifer, so refer to those rules. – unsigned comment by 178.25.109.106
- Actually, it probably generates water even more rapidly than an aquifer - if you've ever played 40d and embarked with one of those "waterfalls from nowhere", then that's what "river source" tiles are like. --Quietust 02:48, 5 December 2010 (UTC)
