Inexpensive, Hands-on Venturi Meter Learning Tools: Design, Manufacture, Test, and Implementation*

Hands-on learning devices follow the "learn by doing" paradigm, giving students a deeper understanding of theoretical lessons. However, due to expensive equipment and limited time, not all educators have access to a suitable educational platform. That's why we have developed the venturi meter desktop learning module to provide effective fluid mechanics instruction at a reasonable cost. This module allows students to experiment with fluid flow in the classroom or laboratory and learn the basic principles behind the venturi meter. This study reports on the design, manufacture, testing, and classroom implementation of this low-cost, reproducible, highly visual desktop-sized venturi meter module. Comparison of measured flow rates and associated parameters with corresponding theory reveals its usefulness for demonstrating fluid flow measurement in the undergraduate classroom. Pretest, posttest, and motivational survey results show its efficacy to promote students' conceptual understanding and engagement in the classroom. Therefore, based on the evidence, we can conclude that the developed module can be used in the undergraduate classroom to enhance students' understanding of fluid mechanics concepts and improve their ability to apply theoretical concepts in practice.
