You should be able to solve this

Because if not then you cant prove rockets work in space.

If its in a vacuum then why is the balloon floating?

One day you'll be able to realize FTL manipulations, detection and travel, but sadly, that is not today

its a cylinder through the skin of the container. hell you can even make the entire container one big drum and just take the lid off suddenly. are you 13? do you need me to hold your hand through a physics scenario? can you not make some assumptions yourself?

So is the point you're making that its hard to calculate thrust through a nozzle?

its just a simple thought experiment on the nature of thrust in empty space.

it's just pressure*area but it won't help you because you need to know the ISP of hydrogen through the nozzle

When I was a kid I thought rockets couldn't work in space because there was nothing for them to "push" on, is this what you're after?

but the area of the nozzle is no longer being pushed on by the air. the air can can just fly out into empty space and that kinetic energy is lost.

yes

the area of the hole isn't being pushed on by the hydrogen, but the area across from the hole IS
so it's a net area*pressure difference

aw man why do retards always think they are smart. i mean lost from the system. you think that energy in a circuit isnt lost as heat to the environment?

where does the pressure difference affect the forces. this isnt like a plane wing creating high pressure zones in a medium, this is a medium and a lack of medium. its a big difference.

There is nowhere for the kinetic energy to go except for the rocket/balloon, so the rocket/balloon must accelerate. You can watch this occur yourself by blowing up a balloon and letting it open. It’ll fly around.

its kind of a shame we cant extract all the energy of the gas. i suppose thats where clever valves and thruster shapes come into it.

de leval nozzle, yeah
it works the same way but it gets all the molecules moving in roughly the same direction instead of "however they happen to find the nozzle"

so it makes sure nearly every molecule bounces off the container before leaving into space for each explosion of fuel.
