This lab demonstrates Bernoulli’s principle by measuring pressure changes as water flows through a transparent converging-diverging channel. Vertical pressure taps along the channel connect to manometers or sensors, showing how pressure drops in the narrow throat (where velocity increases) and recovers downstream. A pump maintains steady flow, while a reservoir and scale measure the mass flow rate, reinforcing the trade-off between pressure and kinetic energy in fluids.

The setup provides a clear visual and quantitative analysis of fluid dynamics, ideal for teaching key concepts like continuity and energy conservation. By adjusting flow rates or channel geometry, students can explore real-world applications, such as Venturi meters or aerodynamic design.
