Engineering Specification / Test Plans 14

Major Challenges 15 — Water Leak ¡ Problem: Water was leaking out of bulk head fitting due to uneven surfaces ¡ Solution: Used a Form-A-Gasket to create gasket for uneven surfaces — Electrolysis ¡ Problem: Bubbles were created, but difficult to see ¡ Solution: Used underwater LED lights to emphasize bubbles by reflection of light

Flow Separation 16 According to theoretical results separation angle should occur approximately at 80 O from trailing end for 0.5 in/s flow velocity Separation angle using food dye was approximately at 80 O Separation angle using electrolysis was approximately at 80 O

Uniform Straight Flow Video 17 — Uniform flow velocity throughout test section — Distinct straight streamlines

Budget 18 — Budget for project was $2000 — Team spent ~$1800 — Extra money was spent on buying additional replacement supplies such as platinum wire for future use

Future Design Recommendations 19 — Modularity Design ¡ Completely redesigned to make setup easier — Size of Water Table ¡ A longer and wider water table would allow for straighter flow and a larger test section capability — Higher Voltage for Electrolysis ¡ More bubble generation ¡ Dangerous, but a cover could be made — Deeper Water Design ¡ Deeper water design would allow the high mode on the pump to be used without it surging
