| Aug 31, 2020 at 20:24 | comment | added | DKNguyen | @Ankit For the same volume, to make up for the lack of velocity you need more gas. Stuffing more gas in the same volume gives you more velocity and more mass but I don't think it would work just because you would have to keep pressurizing something more and more and at some point all the pipes and valves would have too thick and heavy. You would hit an engineering limit before the theoretical limit (when your tank is full of gas in the liquid or solid phase hydrogen) at which point you could pressurize no more). Now, if you could have liquid or solid hydrogen, I don't know if that is enough. | |
