Hello everyone.
Please forgive me if I posted in the wrong section, but I have a questions about the simulators.
Would you mind telling me how the simulators are created? What equations are being used? What assumptions are being made?
Also, which simulator would you recommend?
Thank you very much! <3

A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is constructed from thin plastic or other non metallic materials (usually a used plastic soft drink bottle) weighing 1,500 grams or less. The water is forced out by compressed air. It is an example of Newton's third law of motion.

http://www.sciencebits.com/RocketCalculator appears to hold the answers to your question
I use a simulator simply called Water Rocket Computer Model (V4.41) which i downloaded at http://ourworld.compuserve.com/homepage ... 2orckt.htm

hi everyone havent been here for a while RL has been getting in the way , anyway to the point , i would really like this simulator but ...
ourworld.compuserve doesnt exist anymore is it possibe for someone to upload it ?
any way good to be bk

Re: Online Simulator Help!
Nice to see you back.
The original download page was hosted on a different site to Paul's main Compuserve pages (which are now all gone). However the Internet Archive can stilll get you quite a lot of the content, and I found the link to the simulator download page.

I'm also attaching the zip file here, but you may have to check the page above for instructions.

Re: Online Simulator Help!
The new location of this seems to be here: http://grosse.is-a-geek.com/paul/h2orckt.htm
... unfortunately, the download link doesn't work. But that site has some useful information about water rocketry, so it's worth visiting.
There's another very good simulator here: http://www.seeds2learn.com/rocketSoftware.html
The downloads are available for Windows, Mac, and Linux.

Re: Online Simulator Help!
And to answer the original poster's question, I have a full mathematical explanation and a Google Sheets simulator available here: https://www.nablu.com/p/water-rocketry.html
I believe my simulator accounts for more factors than any others I have seen, such as the effects of humid air inside the tank, air density due to atmospheric conditions, and choked airflow speed determined by adiabatic cooling changing the speed of sound.
