I work at a tractor dealer and a couple used tractors we got in recently have had water as ballast. Being from a cold state I have never seen this before and I’m glad I checked air pressures and noticed it was water before they froze.
I want to build a replica of a submarine from a game I play, but I don’t know how much I will need to fill the ballast tanks. Can anyone help me out?
As per IMO guidelines, on-board Ballast Water Treatment(BWT) systems will soon need to be installed on most ships. There are several manufacturers of BWT systems offering different treatment systems – UV systems, chemical injection systems & electrolytic system. There are several factors which need to be considered to choose a system which is best suited to a particular vessel.
Additionally, ship owners will also be needed to make the decision to either install exhaust gas scrubbers or to switch to low-sulphur marine fuel oil.
In co-operation with our partners, we offer you turnkey solutions for the installation of Ballast Water Treatment Systems & Scrubber Retrofit on-board, helping you choose the right system and thereby reducing costs and increasing efficiency. Our range of Services include:
· Technical & Economic based evaluation
· On-board Survey & 3D Laser Scanning
· Feasibility Studies & Virtual Installation
· Classification Drawings & Pre-fabrication
· Installation & On-site Supervision

What is the fastest way to get water out of a big tank? I have now 9 big fluid pumps but it does still take an hour or so to get my Ballast tank (200k liters) empty. Is there any better way to do it? What are the limiting factors?
Just wondering, I can go build a rig to test it out I guess, but if anyone can give a quick answer: does water "move" within ballast tanks? IE in a single large tank, will it fill a "deep end" first and so shift your centre of gravity? I'm concerned about ballast tanks being unstable and amplifying trim problems in a sub...
I've played around with water dynamics and whatnot in the past but I've only ever created boats. I need to create a platform that will tip or sway only minimally when im landing a rocket on it.
Pineapple express autoflower - I have only given it distilled water thus far. I was thinking today to add this, to early? any need? How does my plant look - this is my first. went into tent on may 20th- 600w mh viviosun grow light I have a ballast started at 250w- 400w - now it is at 600w.

My glider (LS1f) came with the water system decommissioned. I don’t know whether it had tanks or bags, or if it still does - but I’d like to bring the system back into use.
Has anyone done this before or know anything about what the next steps might be?
Guys, I've been working on a submarine design that uses side ballasts of air filled with water to become un-buoyant. That works great and once my tanks are full, I am able to sink without using power other than lights.
The problem comes when I try to empty the ballasts of water. If I am above 10m in the ocean, I have no issues. Below that my tanks remain full and nothing happens. I assume this is due to pressure from the depths of the ocean. Is there any solution to this issue? A valve or something I haven't tried? Currently just two pumps and 4 fluid ports.
Thanks!
