Project Proposal
This project will furnish a bench-top unit that
demonstrates laminar, transitional, and turbulent
flow in a pipe using visualization technique
similar to the classic experiments of Osborne
Reynolds. The unit will be used for classroom
demonstrations for beginning (or aspiring!)
engineers. Hence, it must be safe, rugged, selfcontained, and portable. The unit must be
constructed of readily available parts (e.g., from a
hardware store) and cost less than $200.

Results
Produced laminar, transitional, and
turbulent flow regimes
Flow regimes were clearly visible
Reynolds Number for each regime was
within the expect values
Recommendations
Syringe Pump
Better throttling valves
Variable output pump
Dye filtering system (closed system)
Better injection needle
Two additional flanged tubes
(1/4”, 1/2”)
