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. Never think you are on the safe side, especially when trying to trick the game, dwarf fortress water pressure.

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.

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 Date Posted: 30 Dec, pm.

A U-Bend is a channel that digs down, dwarf fortress water pressure, and curves back up. Since water pressure does not propagate through pumps, it is possible to fill a pool from a "pressurized" source using a screw pump without it overflowing. If you pour water in the taller end of the pipe, it will come "up" out of the lower end until the water levels on both sides are equal.

Never think you are on the safe side, especially when trying to trick the game. A technical explanation by Kanddak from the Bay12 Forum outlines in detail what is known of the in-game fluid mechanics from player testing. Dwarf Fortress attempts to replicate hydrostatic water pressure. This is probably one of the most prominent components, as Toady discussed it at length in an interview with gamasutra. In layman's terms, if you have a body of water that is higher than an open space below it such as a tall tower full of water and a hose from it, or a lake over a mine , and an open route between them, then the water at the lowest z-level will be 'pressed' by the weight of the water above it. As a simple model, think of a pipe shaped like a "J". If you pour water in the taller end of the pipe, it will come "up" out of the lower end until the water levels on both sides are equal. 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.

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.

The above behaviour does only apply to finite water sources like murky pools, artificially created reservoirs and any body of water connected to an infinite water source only diagonally. Note that DF water pressure does not exactly match natural hydrostatic water pressure - it fills to a z-level one level lower than the source. This does not work on a vertical basis - water only travels straight up and down to different Z-levels, never diagonally. I found this video answered a lot of my water questions. Your vertical axles or gear assemblies need to be placed above the solid tile of the pump, and there must not be a channel over the walkable pump tile. Note that fortifications do not neutralize pressure. Here is a example we can see how to generate 9Z level pressure, 1Z greater pressure than our input pressure. View mobile website.

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. In the first example Diagram A , we have water taken directly from a flat river used to fill a u-bend. Pressure cannot push water through diagonal gaps between tiles - instead, it will merely flow through if the water level on the other side is low enough. Multiple adjacent pumps will also transfer power between themselves automatically.

A U-Bend is a channel that digs down, and curves back up. Multiple methods can be used to modify Z-level pressures of fluids. A technical explanation by Kanddak from the Bay12 Forum outlines in detail what is known of the in-game fluid mechanics from player testing. Can be used to provide each level with a pool. Use this page to report any issues related to the migration. Accidentally flooding your fortress with magma is considerably more fun than a flood of water. Install Steam. In the first example Diagram A , we have water taken directly from a flat river used to fill a u-bend. As a simple model, think of a pipe shaped like a "J". This will then enter our chamber as 1Z, fall down a single Z and turn into 2Z Pressure. Knowing how to manipulate pressure as needed allows you to quickly move fluids wherever you wish in your fortress allowing you to build things a dwarf can be proud of.
