Dwarf fortress water pressure

There are several mechanisms at work that try to simulate water pressure in game. While on the whole amazingly accurate, there are several unexpected quirks concerning speed and displacement.

Dwarf Fortress features some pretty complex behavior in an attempt to simulate fluid mechanics. One aspect of this behavior is seen in the form of pressure. The basic idea here is quite simple - certain forms of fluids movement exert pressure , causing them to potentially move upwards into other areas. In Dwarf Fortress , contrary to what many people may believe, pressure is not a property of a body of liquid. When a liquid is moved or created with pressure, it attempts to locate the nearest tile on the same Z-level as its destination tile for falling water, this is 1 Z-level beneath its original location by moving north, south, east, west, down, or up. As it tries to locate an appropriate destination, the liquid will first only try to move sideways and downward - only when this fails will it attempt to move upward. Pressure will not propagate through diagonal gaps.

If I have a river on Z 10 as my water source, and my well on level Z 5, with my reservoir on Z 4, can I use the diagonal block method to bring my water pressure down to Z 4 without it flooding it's way back up to Z 5? I know a U bend will only drop you one level from the source. Showing 1 - 2 of 2 comments. Though I don't know the exact answer to your water pressure question, I do know you can always just use floodgates and levers if you're worried about water pressure to create an 'airlock' system on a central cistern which can't overflow. Yes, when water squeezes through the diagonal square it is considered a different water source. I found this video answered a lot of my water questions. Per page: 15 30

Dwarf Fortress does not model surface friction nor air pressure, so the water will not slow in transit nor will 'trapped air bubbles' form.

Wells are buildings that provide access to a water source for your dwarves. A well can be an important feature of a fortress, providing a clean and usually safe water supply compared to rivers , pools and cavern lakes. However, getting water from a well will neither clean nor desalinate it, so you still should make sure that the well has access to clean water. Wells provide an emergency drinking source in case the alcohol runs out don't let that happen! A well is a water source that if constructed correctly will not freeze in the coldest weather, and should last in hot. Enemies that can swim can and will path into your fort through a well. Grates can block underwater threats, but be warned: they cannot stop building destroyers which approach from below.

When the right door is opened, the reservoir provides reduced pressure and limited flow. This is probably one of the most prominent components, as Toady discussed it at length in an interview with gamasutra. Date Posted: 30 Dec, pm. I found this video answered a lot of my water questions. If you put your thumb over the lower end and fill the taller end, then release your thumb, the water will move with remarkable speed, and water will continue to come "up" out that lower end until all the water in the taller part is at the same level as the lower part. It's possible for dwarf-built pumps to pick liquid up and lift it higher, possibly back to the source and thus creating a closed cycle. Use caution when placing a dam on your river. Store Page. When the left door is open, the pressurized water fills a reservoir. It is easy to flood your fortress accidentally by not accounting for water pressure. Water can only flow straight upward, not up and to the side at the same time. The final example Diagram C , demonstrates how a screw pump exerts pressure - in this case, the water fills up to the same level as the pump's output tile highlighted in red. An active control system can allow some water flow while preventing pressurized water from overflowing. As a simple model, think of a pipe shaped like a "J". While there are many different ways to set up a control system, a relatively simple example is shown below:.

Dwarf Fortress does not model surface friction nor air pressure, so the water will not slow in transit nor will 'trapped air bubbles' form. Of course, there is a downside - you still have to run the pumps and due to the source water's pressure, the pump must be powered instead of run by a dwarf , as the tile the dwarf needs to stand on is filled by water. Discussions Rules and Guidelines. A U-Bend is a channel that digs down, and curves back up. Unless pumped, magma does not have pressure it cannot flow up, and doesn't appear to move at greater speeds. In this case, the river is free to flow off the edge of the map, so the only pressure comes from the water tile on the top of the u-bend's left side highlighted in green falling downward into the tile highlighted in red , so the water on the right side stops one level below the river itself, because even though the source tile is at river level, the destination tile in red , whose height the water will reach because of pressure, is one z-level below the source tile.
