Within the intricacies of fluid dynamics, is a device capable of measuring fluid flow without causing excessive pressure loss. Finding its applications, varied industrial domains; venturi tubes are a crucial instrument in maintaining precision and accuracy. Join us as we dive into the world of venturi tubes and explore their important applications.
What are Venturi Tubes?
A cylindrical cross section with narrowed centre portion (flanked by wider ends) accelerating the flow velocity is a venturi tube. Giovanni Battista Venturi designed this marvel based on the Bernoulli’s equation. The concept states that, as the velocity of fluid increases, it experiences a pressure drop. Widely used concept is employed in multiple flow measuring devices.
How a Venturi tube works?
Working of a venturi tube is simple yet quite effective. When the fluid enters the narrow section of the tube, its speed increases, correspondingly raising its velocity. As the velocity of fluid increases, its pressures decrease’s. Once this fluid is exposed to the wider entrance of the tube, its velocity is reduced quickly which builds up the pressure. This pressure developed on the wider section can also be termed as recovery pressure. By measuring the difference in pressures on both the sections of tube, we can calculate the flow rate. Thus, a venturi tube can also be employed for precise flow control and measurement according to the type of fluid flow
Applications of a Venturi tube
