10. Material Selection
Materials are sorted based on Refractive Index to determine which solid – liquid pairs are the best candidates.

11. Concept #1
Flow enters from the hole closer to the motor on the housing, wraps around the motor shaft, flows through the closed impeller and out.

12. Concept #2
Flow enters from the hole closer to the motor on the housing, wraps around the motor shaft, flows through the open impeller and out.
Note: This causes minor problems connecting the impeller blade to the shaft

13. Concept #3
Flow enters from the bottom of the housing, takes 3 right hand turns and enters from the front. Then it goes through the open impeller and exits the housing
