Water Rocket Fun can help students and rocketeers understand the physics of water rockets and how to optimize their launches to obtain the highest apogees. The interface is designed to be easy to use and understand. But don't be fooled by the program;s simple layout, few if any of the other simulators you may find are as accurate. Under the hood this program is pretty sophisticated and thorough. The methodology includes both the incompressible and compressible fluid mechanics along with a fair amount of thermodynamics and numerical methods to provide accurate water rocket apogees predictions. Check out the excellent correlation between simulation and sophisticated high-speed digital camera results at our web site.
