- TL;DR Summary
- Using basic calculator it seems as if a rocket can produce a lot of thrust and use little fuel if you increase pressure within practically possible range:10-20MPA?

Several things I don't understand: is 1cm^2 nozzle with 15.1 Mpa pressure possible? How is the effective velocity calculated especially if you aren't combusting but just open cylinder to release pressure? Why is the mass loss rate negative if you increase pressure? I should've solved this as a polynomial calculation since the calculator gives odd values unless you reload. Thank you.
