Welcome to the Water Rocket Forum, sponsored by The Water Rocket Achievement World Record Association.

The largest, most sophisticated and ground breaking group supporting you, the serious water rocket flyer! Whether you are a beginner or an expert, the WRA2 has something for everyone.

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.

math equation

Post by Moustache » Thu Oct 06, 2016 11:10 am

Hello, from Portugal

I´m new in water rockets, and want learn more. I hope in this forum you could help to understand some math equation, like this one:

h=(Mi/Mr)*(Mi/Mr)*(Pi/density of water*g)

It looks like an equation for predicting the max altitude using the mass of a filled rocket and the mass of the empty rocket, the density of water, and acceleration due to gravity.

Water rocket, is more experience, not theory.


I come from China, do not understand English, your information I use the translation software to view. I like water rockets, technology is the same, I hope we can become friends.
