This study explores the practical application of Bernoulli's equation, a cornerstone of fluid dynamics that describes the conservation of energy in a flowing, incompressible fluid. The experiment utilized a venturi apparatus equipped with a series of manometers and a hypodermic probe, enabling precise measurement of pressure and velocity variations across sections of a duct with variable cross-sectional areas. By applying Bernoulli's equation, we analyzed the inverse relationship between velocity and pressure within a streamline, confirming that as the fluid velocity increased due to constrictions in the duct, there was a corresponding drop in pressure, consistent with theoretical predictions of energy conservation. However, the accuracy of the results was influenced by experimental factors, including the presence of air bubbles within the manometer tubes, which introduced potential sources of error in pressure readings. Despite these limitations, the experiment underscores the relevance of Bernoulli's principle in engineering applications, such as fluid transport systems and aerodynamic design, providing valuable insights into the behavior of incompressible fluids under varying flow conditions.
