The venturimeter has a fundamental principle that is based on Bernoulli’s principle; when the cross sectional area of a cylindrical flow conduit is reduced, a pressure difference is created, this pressure difference is used in calculating the flow rate or discharge through a pipe. The venturimeter can accurately measure volumetric flowrate using Bernoulli’s principle. In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy. Bernoulli's principle can be derived from the principle of conservation of energy. This states that, in a steady flow, the sum of all forms of energy in a fluid along a streamline is the same at all points on that streamline. This requires that the sum of kinetic energy, potential energy and internal energy remains constant. Over time it has been discovered that the common metals being used to manufacture the tanks gets rusted and therefore affects the accuracy of the equipment as corroded metal tanks don’t give exact values when calculating the flowrate and also there is no clear way of checking the water level in the measuring tanks. This project has solved the design problem maintaining functionality, durability and aesthetics, rein enforced fiber glass in the design and manufacturing of venturimeter laboratory equipment. With the help of Solidworks Simulation, a well fabricated frame and rein enforced fiber glass, I have been able to Design and Fabricate a functional, aesthetic and durable laboratory venturimeter apparatus for practical use in the universities. There is no case of corrosion, and the liquid levels in the measuring tanks can be accurately taken with ease due to the transparency of the rein enforced fiber glass
