Abstract: The measurement of velocity distribution and flow visualization of water is important for educational and research purposes, as it allows students to apply theoretical fluid dynamics concepts in practical settings. Flow velocity fields and related properties are obtained using optical techniques like particle image velocimetry (PIV), a non-intrusive method of flow visualization. However, the high cost of traditional setups often presents accessibility barriers to PIV for educational institutions. This study introduces a low-cost alternative that utilizes a fish tank, polyamide tracer particles, a GoPro camera, and a high-power continuous wave laser module. Results indicate that this budget-friendly PIV system can be a viable alternative to traditional low-speed systems, with implications of reducing financial barriers and increasing access to PIV technology in educational settings.
