Bernoullis Theorem Apparatus (SMT-FM-01)

Bernoulli’s theorem explains the relationship between the velocity and pressure of a fluid in motion, showing that an increase in velocity results in a reduction in pressure while the total energy of the flow remains constant. This principle, which is also described as the conservation of energy in fluid flow, is widely applied in various engineering fields including aerodynamics, hydraulics, and pipeline system design. The apparatus provides a practical way to study and verify this fundamental law of fluid mechanics in a controlled laboratory environment.

The unit consists of a pipe section fitted with a transparent Venturi nozzle and a movable Pitot tube used to measure total pressure. The Pitot tube is placed inside the Venturi nozzle and can be adjusted axially, with its position visible through the transparent panel of the nozzle. The apparatus also includes a manometer panel with transparent tubes mounted against a back sheet engraved with scales, making it easy to observe and record pressure differences. Its structure is designed to resist corrosion, ensuring durability for repeated use.

The equipment is compatible with a hydraulic bench, such as the ESOLS Hydraulic Bench (SMT-FM-100), or other similar laboratory water supply systems. It allows students and researchers to visualize the relationship between velocity, pressure, and energy conservation in fluid flow, providing clear insights into the working of Bernoulli’s principle. This makes it an effective teaching and learning tool in fluid mechanics laboratories.
