Alright what i am trying to do is to find the proper ratio of water in a water bottle.

The Bottles are

591 ml

and 2 L

I am trying to figure out the equation to get the maximum height of the rocket.

Does anyone know how i can get this equation ?

i havent factored the gravitational force that would be affecting the rocket as i am thinking it would be a constant through out the equation. If i am wrong please tell me.

I am using a standard air nozzle from a car tire to pump the air into it.

I am also thinking of making the radius of the bottle smaller inside the water bottle to have the thrust last longer. Does anyone think thats a good idea? as a smaller hole would just make the pressure release slower.

Thanks in advance
