Introduction. An Orifice Meter is basically a type of flow meter used to measure the rate of flow of Liquid or Gas, especially Steam, using the Differential Pressure Measurement principle. It is mainly used for robust applications as it is known for its durability and is very economical. Online calculator to quickly determine Steam Flow Rate through an Orifice. Includes 53 different calculations. Equations displayed for easy reference.
Restrictive Flow Orifices The Restrictive Flow Orifice (RFO) is for use in conjunction with high purity compressed gas applications in both the semiconductor and allied chemical industries. Matheson Tri-Gas pioneered the development of RFO technology. Restrictive Flow Orifices are used to limit the potential danger of an uncontrolled flow from File Size: 59KB. Experiment No Flow through Venturi meter Background and Theory Introduction Flow meters are used in the industry to measure the volumetric flow rate of fluids. Differential pressure type flow meters (Head flow meters)measure flow rate by introducing a constriction in the flow File Size: KB.
SUMMARY A fluid mechanical model of the acoustic behavior small orifices is presented which predicts orifice resistance and reactance as a function of incident sound pressure level, frequency, and orifice geometry. Agreement between predicted and measured values (in both water and air) of orifice impedance is Size: 1MB. - These are devices that have applications in flow measurement. The manufacturers should be contacted for friction and turbulence losses in the stream.

As an example of the application of free streamline theory, let us calculate the contraction ratio of a two-dimensional jet of liquid emerging from an orifice. Suppose that the orifice in question is a long thin slot in a plane wall of small thickness, and that the wall forms part of a large vessel containing liquid.
F orifice and free jet flow apparatus, with two orifices having diameters of 3 and 6 mm; Measuring cylinder for flow measurement; and; Stopwatch for timing the flow measurement.
Equipment Description. The orifice and free jet flow apparatus consists of a cylindrical head tank with an orifice plate set into its side (Figure ).Author: Habib Ahmari, Shah Md Imran Kabir.
Experiment (5): Flow through small orifices Introduction: An Orifice is an opening in the side or base of tank or reservoir through which fluid is discharge in the form of a jet.
The discharge will depend up on the head of the fluid (H) above the level of the Size: 1MB. Flow through an orifice Let us consider one tank with a circular orifice fitted at one side of the tank as displayed here in following figure.
Liquid flowing through the orifice is developing a liquid jet whose cross-sectional area is smaller than the cross-sectional area of the circular orifice.

TUTORIAL No. 1 FLUID FLOW THEORY fluid to run through an orifice of very accurate size in an agate block. 50 ml of fluid are allowed to fall from the level A stream line is an imaginary line with no flow normal to it, only along it.
When the flow is laminar, the streamlines are parallel and for flow between two parallel surfaces we may File Size: KB. Consider an orifice is fitted with a tank. The liquid particles, in order to flow out through the orifice, move towards the orifice from all directions.
A few of the particles first move downward, then take a turn to enter into the orifice and then finally flow through it.

Orifices and its types-small and orifices, free and drowned orifices. Flow through (a) Sharp edged small orifices & loss of head at sharp edged small orifices.
(b) Sharp edged Large orifice of Rectangular shape. (c) Drowned orifice (sharp edged or bell mouthed) of any shape. Rankine’s theory-its assumptions and application in. To change the level in the tank (and so the head on the orifice), students adjust the flow to the diffuser.
Water leaves the tank through the orifice. The jet that leaves the orifice discharges into the hydraulic bench measuring tank. TecQuipment’s Flow through an Orifice apparatus allows students to measure: • Decrease in flow • Contraction of the stream • Energy loss.
Since under the free flow conditions, the jet emerging out from the orifice into the air therefore, atmospheric pressure prevails over the cross-section of the jet (Fig. 1a).For fully submerged orifice (Fig. 1b), water level in the diverted channel is above the upper crest of the jet coming out of the orifice is within water and experiences higher pressure than free by: 7.

TecQuipment’s Flow through an Orifice apparatus allows students to measure: Decrease in flow; Contraction of the stream; Energy loss; They find these measurements as water leaves an orifice. Students can also use the apparatus to study different shapes of an orifice (extra orifices are available separately, H4a).
Sub-Critical and Super-Critical Flow Up: Incompressible Inviscid Flow Previous: d'Alembert's Paradox Flow Through an Orifice Consider the situation, illustrated in Figurein which a horizontal jet of fluid emerges from an orifice in the side of a shown in the figure, the jet narrows over a short distance beyond the orifice that is comparable with the jet diameter to form what.
push twice as many fuel particles through it at twice the velocity, so we will have to do 2 x 2 or 4 times the work. We use the pressure to do this work. If you want to flow more through an orifice, but keep the pressure the same, then you must use a larger orifice.
The flow increases as the area of the orifice. Theory: Orifice flow. I've got friction less fluid, and my points are along a stream line. Meaning that I can get from point one to point two, as the fluid moves along the conduit. so first, assume that H1 is equal to H2.
The second thing, is that if you look at the, the area that the, the flow is going through, and again I've drawn.
