Osborne Reynolds Fluid Flow Demonstration Senior Design Project EML 4552 Group #1 John Curry Antoine Berret Edmund Laryea Michael McIntyre Topics of Discussion Project Proposal Design Selection Final Design Results Conclusion 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, self- contained, and portable. The unit must be constructed of readily available parts (e.g., from a hardware store) and cost less than $200.
