Introduction
Providing accurate fluid dynamics experiments for undergraduate laboratories is challenging in several ways, including reproducibility, simplicity, and accessibility to introductory students. The data from many introductory experiments, for example, is not sufficiently accurate to test whether a linear or a quadratic relationship more appropriately models the dependence of drag force on velocity. An optimal laboratory experiment is sufficiently inexpensive for multiple groups of students to perform with accurate, repeatable results. Examples are plentiful in undergraduate kinematics laboratories, including simple harmonic oscillators and sliding block experiments. Cost-effective and accurate experiments in fluid dynamics are less common.
Video cameras with good resolution and frame rates from 60-240 frames per second are widely available, providing an opportunity for cost-effective access to accurate experiments in fluid dynamics. This article provides an...
