FLOW THROUGH VENTURIMETER

This experiment focuses on fluid flow measurement using a Venturi meter, emphasizing its application in determining flow rates accurately across industrial systems. The Venturi meter operates by channeling fluid through a constricted section, creating a measurable pressure drop as velocity increases at the throat. Key objectives of the experiment are to derive the discharge coefficient (Cd) from empirical data and to analyze the relationship between Reynolds number and Cd , providing insight into the performance of the Venturi meter under varying flow conditions. The setup includes a closed-loop water system with a Venturi meter, orifice plate, and rotameter, each equipped with pressure taps for measuring differentials across the devices. Using Bernoulli's equation, theoretical flow rates are calculated and compared to actual measurements obtained by catch-tank and stopwatch methods, which serve as the control standard. Additionally, energy losses incurred across pipeline components, including elbows and rapid expansions, are assessed, illustrating how different devices impact fluid dynamics. This experiment reinforces fundamental fluid mechanics concepts and demonstrates how Venturi meters enable precise flow measurement in industrial settings, underscoring the importance of calibration and measurement accuracy. The results validate the reliability of the Venturi meter and deepen understanding of practical flow measurement technologies essential in engineering applications.
