Of water pumps, pressure, and Fun.
« on: March 31, 2010, 03:17:19 am »

Thank god I was only going one frame at a time, otherwise this could've been a disaster.

Let's just say that two pump towers that draw their water from the base of a large three story tall cistern provide *obscene* amounts of pressure. I was expecting four pump towers (Two on the east, two on the west) to be able to adequately feed my five planned waterfalls. Turns out, I could've provided more than enough water with half that.

Water is, quite literally, traveling horizontally while in mid air. And not just a stray drop or two, but a total of seven tiles surrounding the center waterfall are at 7/7 depth and another is at 3/7 on the z-level directly below my plumbing. For reference, the water has only fallen a total of three z-levels on the waterfall contained by windows (Ie forced down a 1x1 chute).

Oh god...

I'll be able to cut off the water feed, but it'll be several dozen frames until my fastest dwarf could get there...

So much for showing off a partially completed waterfall system for the next spring upload, haha.

Edit: 24 tiles of open space around the central waterfall now contain water. Most are 7/7.

*Whimper*

2nd Edit: These two water pump towers are feeding a 25 tile large water fall...and still flooding my level directly below the plumbing.

What. The. Fuck.

3rd Edit: Hahaha. Oh god. The 25 tile large waterfall just hit my ground floor. The problem? The ground floor only has a 1x1 hole in the ground for the central waterfall.

Ahahahaha.

I have almost completed the first half of my bottom-to-top quadruple magma pump stack that I plan to use for a great fountain in the new dining hall, multiple magmafalls (both interior and exterior) and a lava river. I hope this project goes as well as the last dining hall where I had the place submerged in 1/7 magma for months. I also lost much of my booze due to flaming dorfs.

Wait... The next version... My precious plans! Oh curse you with your new and shiny release!

The water was finally shutoff. The damage *would* have been minimal, except that I accidentally pulled the base magma hatch lever instead of the base water hatch one. Fortunately, the magma pumps weren't quite setup to run yet, so that didn't cause me to burn my fort down. However, combining the delay in pulling the base water hatch lever and the fact that my top water hatch lever got submerged early on, yea...

I'm going to upload the giant mess just show how fucking awful things are, haha.

Your panicked cries of WTF remind me of why this game is so awesome.

I'll wager exactly 6 survive, after the drowning and tantruming die down.

I'll add now that two z-levels of water don't break a fall ;p

Edit: Looks like the Fun's over.

Total casualties: Two dwarves and one war dog. All would've been avoided if I hadn't removed my safety grates a couple years back to enhance the look of the catacombs.

On the upside, most of my dwarves are now at least dabbling swimmers! Woot!

Wow. The sheer ridiculous opulence of that tower is crazy, and it's all the crazier since to do this you'd need to be really unfamiliar with large-scale pumping.

Well, good luck clearing all the mud off those floors... I hope you have a lot of furniture and a lot of patience.

The problem was that I didn't realize just how often water pumps would pull the water up.

I had assumed that two pumps would bring up enough water to "fill" three water falls to a bit under max capacity. I hadn't even thought that it would've been possible for the pumps to "tick" more often than gravity, let alone the possibility of water traveling horizontally in mid air.

Haha.
A single pump is sufficient to run about thirty waterfalls. ( http://www.bay12games.com/forum/index.php?topic=50751.0 )

I know what you mean - I've started building safety structures and just hiding them since my last messup with them, though. Good stuff all around! Most Fun I've seen in a while.

Yes, a single pump can move staggering amounts of liquid.

Get a little pressure under the initial pump and its amazing at the kind of flow you can get from just one single pump, either pumping water or magma.   :o

I had a flushing system for my holding tank trap, so after the bridges retract and collect all of the uninvited guests into the holding tank I can then flush them into my exploding pit.

1 pump put water into the chamber on one side, and 6 pumps removed it on the other side of the chamber so the exploring pit itself would not flood.

Could not keep up with the capacity. Not even close. It would actually drown goblins, traders, and nobles before flushing them down the pit. I wanted a very slow, gradually building wall of water that would gently nudge them to their doom.

The single pump was fed with only 2 levels of water for pressure.
