I have a bet with one of my friends,
it has to do with the bernoulli equation that says the higher the velocity of a gas, the lower the pressure.
I came up with an invention idea that involves a gas cylinder, the gas cylinder has a maximum pressure of 4000 PSI and the gas inside exerts that maximum pressure.
in order to increase the volume, a spinning rod is placed in the center of the canister, and spins the gas so that the gas at the edge of the canister moves at a high velocity relative to the wall of the canister,
My hypothesis is that this velocity forces the pressure differential of the canister walls to decrease thus allowing for a greater volume of air inside the canister.
My friend said that it won't work, because he said that the hydrogen gas at that pressure is incompressible, and buy putting more air into the can you'd have to increase the density,
he said to imagine water spinning around in a can there are no air bubble inside the can, it is filled to the brim, the faster you spin it, (neglecting the centrifugal force) the pressure decreases on the sidewall of the can, but if you were to put more air inside, it would be as if the liquid were solid, it might not shoot out of the can, it would just stay there, and if you were to push more water into you couldn't because you'd have to increase the density, and that requires a huge amount of energy.
So I said, no that's wrong
and now we are in a bet for twenty five cents
