Abstract: Interpreting the interdependence of pressure, velocity, and elevation heads in fluid flow is critical for understanding fluid behaviour and for designing efficient engineering systems Bernoulli’s theorem, which describes the conservation of mechanical energy along a streamline and quantitatively relates pressure, velocity, and elevation heads, serves as the fundamental theoretical framework for the present study. This experimental research aims to design and fabricate Bernoulli's apparatus for demonstrating the principle and measuring the discharge and flow rate of fluids. The apparatus consists of a smooth, narrow flow channel with gradual contraction and expansion sections, pressure taps, and flow rate and discharge measurement devices. The fabrication involves selecting suitable materials, fabricating the flow channel, installing pressure taps, and integrating flow rate and discharge measurement devices. The experimental setup includes connecting a fluid supply, controlling the flow rate, measuring pressure and discharge, and analyzing the data to verify Bernoulli's principle and calculate flow rate and discharge. Experimental results exhibited well-defined pressure head variations along the test section, aligning closely with theoretical expectations, and enabled accurate calculation of both theoretical and actual discharge The apparatus provides a practical tool for students and researchers to visualize and quantify fluid flow behavior, enhancing understanding of fluid dynamics and hydraulic engineering principles.
