The final geometry of the water slide been determined and analyzed. The team used two different methods of performing dynamics analyses to model the theoretical velocities and accelerations of a rider going down the slide. One method was based on the idea that the rider will be slowed primarily by friction between themselves and the slide, and the other was based on the idea that the rider would be slowed by the dispersion of their kinetic energy as they were guided by the slide's walls. Both analyses provided the same results. A rider on the slide would theoretically obtain a maximum speed of 26 miles per hour and experience up to 0.65 Gs of acceleration.

ASTM F2376, the Standard Practice for Classification, Design, Manufacture, Construction, and Operation of Water Slide Systems, which governs the design of water slides in the United States, allows for a maximum of 2 Gs of acceleration on the rider. Since the team's design conforms to the standard, the proposed water slide geometry was finalized. Technical drawings showing the geometry were made and are shown below. The flow analysis is now underway to determine the pumping system requirements and do a secondary safety check.
