flow through a venturi meter

Back to HOME. The Venturimeter is used to measure the flow rate of compressible and incompressible fluid through a pipeline.

It is based on the use of the Venturi effect the reduction of fluid pressure that results when a fluid runs through a constricted section of pipe.

. The meter can measure the fluid flow and reduce its flow when necessary. The change in pressure in the fluid as it passes through the meter can be used. The objective of this experiment is to study the axial distribution of pressure and velocity of a fluid flowing through a venturi meter and to measure the discharge through the pipe by using LabView.

Parts of Venturi Meter. The area of cross sections of pipe at ends where the venturi meter has been connected are A1 and A2 respectively. Close the apparatus flow control valve.

FLUIDS MECHANICS1 4. It works on the basic principle of Bernoullis Equation. EXPERIMENT TO STUDY FLOW THROUGH A VENTURI METER.

Read customer reviews find best sellers. It has a tube of broad diameter and a small constriction towards the middle. The principle of venturimeter is that when a fluid flows through the venturimeter it accelerates in the convergent section and decelerates in the divergent section resulting in a drop in the static pressure followed by a pressure recovery in the flow direction.

It creates a flow through the tube. Let P1 and P2 are the pressure of fluid at the two ends 1 and 2. Apply for Nodal Centre Program.

A venturi meter is a device that is used to measure the speed flow of incompressible fluid through a pipe. Convergent-Divergent Venturi meter. A Venturi meter is used to measure the flow rate through a tube.

The corresponding velocity of fluid are v1 and v2. FLUIDS MECHANICS1 4. Venturi Meter is a device in which pressure energy is converted into kinetic energy and it is used for measuring the rate of flow of liquid through pipes.

Table of Contents0000 Online lab experiment introduction0008 Experimental set up0029 The Venturi meter 0058 Venturi meter diameters0208 Experimental obj. Flow through Venturi meter.

To measure the volumetric flow rate of fluids. The Venturi meter demonstrator shows how fluid pressure is reduced when it flows through a constricted section of tubing. Brooks Instrument Is The Global Leader In Flow And Pressure Instrumentation.

Before the constriction pressure builds as air tries to force itself. Fig 11 Venturi Meter Diagram. Before allowing water to flow through the apparatus check that the air purge valve on the upper manifold is tightly closed.

Venturi meter works on the principle of the. To determine the flow rate. A venturi is a converging-Diverging nozzle of circular cross-section.

To measure the volumetric flow rate of fluids. Free online demo. In the middle where the tube constricts the air flows faster and the downward pressure on the water decreases.

According to Fluid Handling Pro It starts with qualifications of non-viscous steady incompressible flow at a constant temperature. EXPERIMENT TO STUDY FLOW THROUGH A VENTURI METER. It is invented by American Engineer Clemans Herchel and named by the Italian physicist Giovanni Venturi.

Flow through Venturi meter. Ad Building High Quality Flow Products Since 1946. Fig 11 Venturi Meter Diagram.

For better comparisons two separate trials were analyzed and Venturi coefficients for both were computed. The venturi tube operates by increasing the velocity of fluid through a contraction then reverting it back to normal by a slow enlargement to the original pipe diameter. Ad Browse discover thousands of brands.

The venturi meter is connected to a pipe at two points as shown in the fig. The meter in its. To measure the volumetric flow rate of fluids.

Set both the apparatus flow control and bench supply valve to approximately one third their fully open positions. Trial 1 and Trial 2 yielded a Cv of 093 and 092 respectively. The Venturimeter is used to measure the flow rate of compressible and incompressible fluid through a pipeline.

Engineers can measure the change in pressure using Venturi meters and nozzles which tell you the flow rate. - as a result the two meters indicate the difference in pressure by means of a height difference h. We measure the pressure head before and at the contraction to calculate the flow rate using equations based on Bernoullis equation and the continuity principle which will.

Given a Venturi Meter Cv the Venturi coefficient can be determined to compare the actual and ideal values as per Bernoullis predictions for a volume flow rate. Switch on the bench supply and allow water to flow. The change in pressure in the fluid as it passes through the meter can be used.

The device converts pressure energy into kinetic energy and measures the rate of flow of liquid through pipes. How does the pressure change as air flows through a Venturi meter.
