The flow measurement instruments show students the common methods of measuring water flow. They also give applications of the steady flow energy equation (Bernoullis equation). Students use a Venturi meter and an orifice plate meter and compare the losses of each. They also find the losses in a rapid enlargement.

Venturi meter and orifice plate effects are two main and very important phenomenas in fuild mechanics sub field of mechanical engineering. In this post the effect of venturi meter and orifice plate on the fluid flow will be disciussed and complete work will be presented in the form of report. Pipe Flow Measurement - Venturi Flowmeters - Bernoulli's A Venturi requires two pressure and one temperature measurement to accurately determine flow. The first pressure is measured at the Venturi's upstream location, P 1 . This is used for the density calculation and the high side input to the differential pressure measurement. Pitot tube measurement device BritannicaPitot tube, Instrument for measuring the velocity (speed) of a flowing fluid.Invented by Henri Pitot (16951771), it consists of a tube with a short, right-angled bend, which is placed vertically in a moving fluid with the mouth of the bent part directed upstream; the pressure, measured with an attached device, depends on the fluid flow and can be used to calculate the velocity.

Pressure recovery for venturi tubes is a better than that of the orifice meter. Venturi tubes are appropriate for clean, dirty and viscous liquid and few slurry services as well. In venturi tubes, pressure recovery is more compared to other flow measuring devices . Essential upstream pipe length of a venturi tube is 5 to 20 diameters. Venturi Flow Meter Working Principle Animation Applications of venturi meters. It is used where high pressure recovery is required. Can be used for measuring flow rates of water,gases,suspended solids, slurries and dirty liquids. Can be used to measure high flow rates in pipes having diameters in a few meters. Advantages of venturi meters. Less changes of getting clogged with sediments Venturi Flow Meter Working Principle Animation Applications of venturi meters.

May 19, 2015 · Introduction. A Venturi meter is basically a type of flow meter with a specially designed tube, used to measure the flow velocity of liquids especially highly viscous liquids. It is one of the most accurate means of measuring the flow. Just like Electromagnetic Flow meter, it has no pressure drop (head loss) hence is very useful in places where pressure drop should be minimal and where a Venturi meters and tubes Omega EngineeringFlow venturi tube performance is much affected by calibration. The inaccuracy of the discharge coefficient in a universal venturi, at Reynolds numbers exceeding 75,000, is 0.5%. The inaccuracy of a classical venturi at Re > 200,000 is between 0.7 and 1.5%. Venturimeter:Definition, Parts, Working, Derivation 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. It is invented by an American Engineer Clemans Herchel and named by the Italian physicist Giovanni Venturi. It
The venturi version generates a higher differential pressure than does a regular pitot tube. Static Pressure Measurement. In jacketed (dual-walled) pitot-tube designs, the impact pressure port faces forward into the flow, while pitot static tube port do not, but are, instead, spaced around the outer tube. Both pressure signals (PT and P) are measurement Definition, Types, Instruments - BritannicaMeasurement, the process of associating numbers with physical quantities and phenomena. Measurement is fundamental to the sciences; to engineering, construction, and other technical fields; and to almost all everyday activities.

Nov 02, 2020 · THE CLASSIC VENTURI TUBE. The venturi tube, as designed by Clemens Herschel in 1887. It consists of. A cylindrical inlet section equal to the pipe diameter; A converging conical section in which the cross sectional area decreases, causing the velocity to increase with a corresponding increase in the velocity head and a decrease in the pressure head Flow meter device BritannicaFlow meter, Device that measures the velocity of a gas or liquid.It has applications in medicine as well as in chemical engineering, aeronautics, and meteorology.Examples include pitot tubes, venturi tubes, and rotameters (tapered graduated tubes with a float inside that is supported by the flowing fluid at a level that depends on the flow rate).). Ultrasonic flow meters, in which reflecting
