Topics of DiscussionProject ProposalDesign Selection Final DesignResultsConclusion

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.
