ABSTRACT An experimental toolset for efflux‐speed measurement was developed by refining a prototype originally implemented during the COVID‐19 pandemic. A fluid mechanics experiment—the Speed of Efflux Analysis Laboratory—was designed for first‐year engineering students to introduce fundamental fluid dynamics concepts. Tracker video analysis software was integrated to enhance students' digital literacy and support data analysis. The study involved 430 students and a 6‐student focus group. Prior knowledge, learning objectives, suitable apparatus, and curricular alignment were systematically considered in the design process. The experimental setup produced data consistent with theoretical predictions, enabling students to apply the continuity equation and Bernoulli's principle to real measurements. Post‐test scores demonstrated improved understanding, and students effectively used Tracker software to analyze fluid motion. This experiment can be implemented in introductory physics labs to promote conceptual understanding, develop digital literacy, reduce equipment costs, and support flexible lab‐at‐home learning, while enhancing interdisciplinary STEM skills across physics and engineering contexts.
