Can you SWIM on Venus?

[Souper]

Ok.

Let's say we have a super-cooled titanium suit that used diamonds and bulletproof glass for a visor. Also, let's get an exoskeleton on there. Protect it with titanium. Oh, and just a pinch of magic and futuristic science, will ya?

If You want to do stuff on Venus....

...Is it possible to jump up and swim in Venus' atmosphere?

[xxjetterxx]

MY guess is it would be very, very hard.

[Rakaydos]

if you + the suit weigh less than the atmosphere displaced by the suit, you'd float. if the two numbers are close enough, sure, you can swim.

[Ralathon]

I weigh about 70 kg and just barely float in water. So I probably have a volume of 70 liters. Venus has a surface pressure of 90 bar, a temperature of about 460 degrees celcius and mostly consists of carbon dioxide.

Plugging this into the ideal gas law gives me a mass displacement of about 4.5 kg in the venusian atmosphere. So that is more than an order of magnitude too small for me to float.

Conclusion: I can't swim in the venusian atmosphere. I suggest trying it on Titan instead, you could probably fly there if you strap some oversized flippers to your arms.

Venus has a surface pressure of about 93 bar, and a temperature of about 740K.

Under these conditions, A CO2/Nitrogen mixture has a density of about 6.4% that of water. Incidentally, this is about the same density as styrofoam. You almost definitely wouldn't be able to swim in it.

Flying, on the other hand... Well I couldn't find a decent coefficient of lift table for an airfoil in supercritical CO2, but using curves for air (which is less viscous), I reckon you'd be able to strap wings onto your arms and get airborne at a brisk trot.

[Scotius]

In almost Earth-like gravity? With protective gear weighting nearly twice as much as your body does? No way.

[ThesaurusRex]

Probably if said suit was connected to a balloon filled with oxygen, helium or hydrogen, functioning as 'water wings', sure.

Also get some flippers.

With all that you're basically just a human blimp anyway.
