Title: Water/Magma pressure theorizing
Post by: Skie on October 25, 2008, 12:56:45 pm
So let's say I have a reservoir of water, 8x8x8 tiles in size. I open a floodgate at the side of the reservoir, in the middle z-level of it (4 or 5), and let the water flow into a pump/pump-system, which feeds the water back into the reservoir a few levels higher, but not higher than the reservoir's topmost level. Now the pump generates unpressurized water, but the amount of the water in the reservoir increases because the pump is able to create 7/7 water out of a 1/7 water tile.

Which of the following happens:
a) The pump generates more water than there is to expand to, therefore the pressure in the reservoir increases infinitely.
b) The amount and pressure of water reaches an equilibrium where water is fed into the pump just as fast as it generates water.
c) The pressure doesn't increase and the water just circulates normally in the reservoir.

Now if it were a) (or perhaps b?), you could make the reservoir of water into a cannon by opening some floodgates at the top, or by channeling into the roof of the reservoir. And that would be cool.

Anyone tried this out or have some insight on it?

How about magma? It can't flow up, but if you pump some magma into the (top-level + 1) of the reservoir, would that give the magma a chance to expand rapidly?

The "pressure" mechanics is in two words a way to teleport water from the topmost level to the lowest free level so there's no actual "pressure"; water movement speed is quite low so you can't make cannons; why do you think you can make 7/7 out of 1/1? You know, pumps drain water, it's more obvious that pumps will make 7/7 into 5-6/7 because some water will transform into mist.

P.S. U-bend rules.

Well, what got me thinking was these:

http://mkv25.net/dfma/movie-327-fastmagmaworldfloodpart2

The magma is somehow circulated there, but the amount of it stays the same. Is this, though, because pipes slowly regenerate the magma you take from it?

If it's magma went and not magma pool (it has contact with magma on lower levels) then it regenerates.

why do you think you can make 7/7 out of 1/7?


I'm thinking its been said on the main forums, and already once on here, that pumps cause 1/7 water to turn into 7/7 when pumped through.

I should check it now :D.
