A chamber could be designed to blow in air and pump out water (initially through vents, later via a handheld hose for catching globs) and separate the suctioned air and water via a centrifugal dryer and possibly a refrigeration-type dehumidifier at the final stages.However, there's also another earth technology which could be quite applicable to initial separation: air bladder water tanks.

Learn more about Stack Overflow the company Discuss the workings and policies of this site I love the swimming questions. Anybody can ask a question Mixed water and air environments could indeed be quite dangerous in microgravity. On earth you can pump water out and air in because the water stays at the bottom and air at the top... here it would break up, float around and be hard to get out. If you enclose the water in a tank, then you can "swim underwater" - but getting in and out the water might be complicated.To swim in water you need to breathe air with only a small content of water droplets. By Tesarra in forum Off-Topic Babbling
The Smoke Ring contains numerous "ponds," globs of water of various sizes which float free like everything else. If two droplets hit themselves at low speed they may unite, but for larger speed the result will be even more droplets in air. A sealed room would remove the air mixing issues. Anybody can answer There is no force removing the air bubbles and water droplets like we are used to when swimming on Earth.
If you inhale too much and too often water instead of air you are in danger of drowning.In zero gravity and under the influence of swimming, there will be many water droplets floating around in the air and air bubbles within the water. Then the swimmer would drown inhaling the floating soup of water fragments. They are then free to open the water door, and enter the water environment.To exit the water environment, they pass through the door into the bladder and close the door behind them.
You need to know when it is possible to open your mouth and take a deep breath of pure air. Detailed answers to any questions you might have Getting enough water into orbit to allow a human to swim might be more challenging though. By using our site, you acknowledge that you have read and understand our Space Exploration Stack Exchange is a question and answer site for spacecraft operators, scientists, engineers, and enthusiasts. An astronaut wanting to move from the air environment into the water one would enter the airlock, don the breathing apparatus and zip themselves into a flexible bladder connected to the water side door.
You pick the launch date. But an all-water environment should be possible. I believe there have been some experiments done with small fish in space that might apply. The air pressure in the surrounding chamber would then be slightly raised, while that inside the bladder lowered, effectively "vacum packing" the astronaut (but only weakly, so that they can continue to breathe). So I think swimming in zero gravity is not possible.
As mentioned in other answers, water has When the radius of the sphere becomes large (on the order of meters), the internal motion of the water in the sphere (and this includes currents induced by swimming and pushing the water around) has As the sphere gets huge, it may take time to create the air pocket inclusions, and Off the top of my head, two issues for free swimming (no breathing gear) I can think of:"lets imagine a ball of water with a 5m radius floating in empty space within a suitably large space station"The sphere of water would break apart from the turbulence caused by the swimmer. By Totally Skeptical in forum Science and Technology More practically the water is valuable so, I suspect you could do something with a suction hose running through a centrifugal dryer before blowing back into the chamber. Have there been birds (or butterflies or insects) flying on the ISS? In zero gravity, water will tend to pull itself into a floating sphere, unless it's completely contained, in which case you wouldn't have a surface to enter through. What does 0G do to If you have a large sealed room containing only water (and obviously give the swimmer some sort of breathing apparatus), it might be a different story. How easy would it be to exit the water?The latter question may have an answer of "just pick up enough speed and you'll just 'fly' out, but the way water likes to So, assuming we can afford the cost of getting a few tons of spare water into orbit, Two major problems present themselves right away. Two possible uses for a true stadium are team-sports, and zero-gravity flying, neither of which would be … As long as the weather is favorable and the pilot is available, you can experience the …
