Measure Flow Rate Using Venturi Meter
Measure Flow Rate Using Venturi Meter. For the measurement of flow rate, the venturimeter is fitted between the pipe of which flow rate is to measure. Experiment 2 flow meter demonstration rig abstract goal of this experiment is to study the flow rate measurement with comparison of pressure drop by utilizing three basic type of flow measuring technique, rotameter,venturi meter and orifice meter and to investigate the loss coefficient of fluid through 90degree elbow.
The pressure difference caused by the constriction is correlated to the flow rate using bernoulli's theorem. Hence, a venturi meter is used to measure the rate of flow of fluid flowing through a pipe. The downstream bore of the orifice is chamfered at 40° to provide an effective orifice plate thickness of 0.35mm.
Negligibly Small Between The Ends Of A Contracting Duct It, Along With The Z Terms, Can Be Omitted From Equation (1) Between Stations (A) And (B).
To calculate the flowrate of a fluid passing through a venturi, enter the parameters below. These changes can be used to measure the flowrate of the fluid. Experiment 2 flow meter demonstration rig abstract goal of this experiment is to study the flow rate measurement with comparison of pressure drop by utilizing three basic type of flow measuring technique, rotameter,venturi meter and orifice meter and to investigate the loss coefficient of fluid through 90degree elbow.
Venturi Meter Or Venturi Tube Means, The Device Measures The Velocity Or Flow Rate Or Discharge Of Fluid In The Pipe.
Using the measured flow rate, pressure drop data, and diameter values, obtain cv using the slope from a linearized plot. The venturi meter is placed in a pipe carrying the fluid. Here we have considered two cross section, first at the inlet and the second one is at the throat.
By Measuring The Difference In The Pressures At An Axial Station Upstream Of The Convergent Section And At The Throat, The Volumetric Flow Rate Can Be Estimated.
The venturimeter is used to measure the flow rate of compressible and incompressible fluid, through a pipeline. A venturi meter is used to measure the flow rate through a tube or volumetric flow rate, q. A fluid passing through smoothly varying constrictions experience changes in velocity and pressure.
The Pressure Difference Caused By The Constriction Is Correlated To The Flow Rate Using Bernoulli's Theorem.
In the converging section of the venturi meter, the flow is accelerated continuously, and therefore, the losses are considered small. The venturimeter is used to measure the rate of flow of a fluid flowing through the pipes. Hence, ¥ 3= 8 6 5 6= ¼ à ì.
Then By Using Bernoulli’s Equation And Continuity Equation We Can Easily Calculate The Flow Rate Through Pipe.
Figure 2 shows an orifice meter with the variable position of vena contracta with respect to the orifice plate. Flow meters are used in the industry to measure the volumetric flow rate of fluids. It has a tube of broad diameter and a small constriction towards the middle.
