Flow in a venturi meter refers to the rate at which a fluid passes through the device. The flow of fluid is measured by the pressure difference created between the converging and diverging sections of the venturi meter. This pressure difference is directly related to the flow rate of the fluid passing through the venturi meter.
Flow can be measured using instruments such as flow meters or by calculating flow rate using the formula Q = A * V, where Q is the flow rate, A is the cross-sectional area of the flow, and V is the velocity of the fluid. Measuring devices like mass flow meters, ultrasonic flow meters, and electromagnetic flow meters are commonly used for measuring flow in various industries.
The stream function for an incompressible flow is a mathematical function that helps describe the flow properties by showing the flow direction and velocity at any point in the flow field. It is used to visualize and analyze the flow patterns and streamline shapes in the flow field.
What is a continuous flow and unsteady flow
Uniform flow occurs when the fluid velocity and properties are constant throughout the flow field, while non-uniform flow has varying velocity and properties across the flow field. In uniform flow, streamlines are parallel and the flow is steady, whereas in non-uniform flow, streamlines may converge or diverge and the flow can be unsteady.
Steady flow: Water flowing through a pipe at a constant rate with uniform velocity is an example of steady flow. Non-steady flow: Waves in the ocean where the water motion is constantly changing in both intensity and direction represent non-steady flow.
Because, the scientist name VENTURI had discover that device as flow measurment. So that it call as venturimeter.
Measurement of flow rate in a pipe
to measure the flow in any pipes
The coefficient of discharge (Cd) for a venturimeter typically ranges from 0.95 to 0.99. This high value indicates that venturimeters are efficient flow measurement devices, with minimal energy losses during fluid flow. The exact value can vary based on factors such as fluid properties, flow conditions, and the design of the venturimeter.
The coefficient of contraction (Cc) for a venturimeter is the ratio of the area of the throat (narrowest section) to the area of the inlet (largest section). It accounts for the loss of fluid flow due to the contraction as the fluid passes through the throat, typically ranging from 0.6 to 0.9 for most venturimeters. This coefficient is crucial for accurate flow rate calculations and reflects the efficiency of the venturimeter design in maintaining fluid velocity.
What is the working principle of venturimeter?
The conclusion of a venturimeter experiment typically demonstrates the relationship between fluid velocity and pressure difference in a flowing fluid. According to Bernoulli's principle, as the fluid passes through the narrower section of the venturimeter, its velocity increases while the pressure decreases. This pressure difference can be used to quantify flow rate, confirming the device's effectiveness for measuring fluid flow in various applications. Overall, the experiment validates the principles of fluid dynamics and flow measurement.
Venturimeter is the short pipe having two conical parts and portion of uniform cross section between these two parts.

venturimeter, orificemeter are some of the instruments used to measure the flow rate in pipe.
Yes, reversing the inlet and outlet connections of a venturi meter will result in flow measurement errors. The design of the venturi meter relies on the inlet and outlet connections being in a specific orientation to accurately measure fluid flow rates. Reversing the connections disrupts the flow dynamics and can lead to inaccurate readings.
A Venturi meter is a device used to measure the flow rate of fluids in a pipeline. It consists of a converging section followed by a throat and then a diverging section. The pressure difference between the converging and throat sections is used to determine the flow rate of the fluid passing through the device.
