I mean a bladder can’t even hold a fifth of a gallon (more like 500ml) so we are already saying it is not possible but assuming there in the future is a human cyborg or a robot the same mass and volume as a human, they would need 60psi and 3.33 gal capacity for two seconds. This info is based on water powered jetpack companies that do this service. So, I did over look one thing: the jetpacks are dual and attached to your legs and they happen over water so not sure the rest of the calculations because I am not certain whether each jetpack has same psi for it to work or it is a combined psi and the water just comes from a hose so there is no capacity but the speed needs to be at least 100gpm.
You may need to double the flow. With the water powered jet packs the water isn’t just being accelerated from a standstill. The water is first flowing up with close to the same speed and is redirected down. So the momentum exchange is twice what it would be if the water were stored in tanks with the flyer.
Yea, I previously just learned that the psi depletes as soon as it leaves the contraption because there is much less pressure, and it is just speed coming out.
That would be a challenge to find out. Because I would look for the material with the minimum durability, not just a metal tank, lol. Like what is the weakest material that can still withstand this type of thing.
Well, for a minute of water jetpack it is 100 gpm, so I divided 100 by 60 seconds to get 1.6… for one second so two it would be 3 and a third gallons for two seconds assuming the right pressure of 60 psi.
3.2 gallon bladder to achieve 2 seconds? And what kind of pressure are we talking, would it just like totally blow your dick off or what

what material would a bladder need to be made out of… hrm hold pls

Silicone Rubber
Polyurethane (PU) Elastomers
Thermoplastic Elastomers (TPEs)
or traditional latex rubber
I remember learning a bladder begins to spasm at 600mL, so we could actually use this spastic pressure to help us levitate. In this paper, I propose…

60 psi is definitely in the “rip your dick off” range
We can only go 15-20 psi. I was taking the scenario as theoretically there was a human anomaly out there that could handle it lol.
pretty sure it’d blow more than just your dick off. it’d be a pretty gruesome scene.
