Development and Test Performance of a Benchtop Venturi Tube

Abstract

A Bench Top Venturi tube was developed in this study. The specific objectives of the study were to; develop a benchtop Venturi tube using locally sourced materials, determine the relationship between the volumetric flow rate or discharge of the Ventri tube and the pressure head and validate the experimental result. The components include a 0.5hp water pump, a control switch, water tank, 5 manometers, a Venturi tube, inlet and outlet control valves, inlet hose, discharge hose, hydraulic bench board. However, successful test runs of this bench top Venturi tube at its design operational parameters shows that the bench top Venturi tube is a good apparatus for learning. The construction of the Venturimeter was based on the knowledge gained from the workshop technology practice, fluid mechanics, engineering drawing and technical drawing and researched work. The results were analysed and compared with a standard Khurmi (2006) analysis of flow discharge through Venturimeter and was in good agreement; hence confirming the usefulness of the Bernoulli’s principles and continuity equation in the analysis of flow discharge through Venturimeter. The proposed concept is a highly effective solution for the precise control and measurement of fluid flow in various industrial settings, such as oil fields, irrigation systems, automotive industry, wastewater treatment plants, and collection systems. The portable benchtop Venturi tube is designed with an easy-to-assemble and disassemble feature, making it incredibly convenient for use. This flow system is an invaluable tool for practical demonstrations in fluid mechanics studies within Mechanical Engineering Laboratory, facilitating precise fluid control and measurement. Moreover, the affordability of this system makes it an excellent investment for businesses looking for cost-effective fluid measurement and control solutions.
