For a water powered jetpack to lift a person it is estimated to need at least 100 gallons per minute, so similarly this could be what would be needed. Even for a second, a person's bladder would need to be 1.6 gallons and expelled at a similar pressure. So not two seconds.
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
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.
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.
