Flow Measurements

This course covers the principles, techniques, and applications of flow measurement in fluid mechanics. It provides a comprehensive understanding of various instruments like the venturi meter, orifice meter, and rotameter, and their operational principles. For instance, the course illustrates how the position of the bob in a rotameter indicates the flow rate, influenced by the fluid's velocity and the bob's weight and buoyancy. It also delves into thermal anemometry, explaining the use of hot wire and hot film methods, their structure, operational principles, and limitations. The course further explores the Laser Doppler Anemometry (LDA), a noninvasive technique that uses the Doppler effect to measure flow velocity. Lastly, it discusses the use of probes, specifically 4-hole probes, in measuring flow parameters such as static pressure, stagnation pressure, and velocity components.
