gas
A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture, such as air, contains a variety of pure gases.

fluid
In physics, a fluid is a liquid, gas, or other material that continuously deforms (flows) under an applied shear stress, or external force. They have zero shear modulus, or, in simpler terms, are substances which cannot resist any shear force applied to them.

What is the main advantage of Orificemeter?
Advantages of Orifice meter:The orifice meter can be easily maintained. Measures a wide range of flows. They have a simple construction. They have easily fitted between the flanges.
Where are orifice meters used?
The orifice plate flow meter is a type of differential pressure flow meter that is commonly used in clean liquid, gas, and stream mass flow measurement.What is the use of Venturimeter and Orificemeter?
Venturi meter and orifice meter are used for measuring the volumetric flow rate of the fluid that based on the continuity equation and Bernoulli's equation.Why is an orifice plate used?
An orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow (in the latter two cases it is often called a restriction plate ).The Differential Pressure Flow Measuring Principle (Orifice-Nozzle-Venturi)
How an orifice is working?
Basic Working Principle of an Orifice MeterThe liquid or gas whose flow rate is to be determined is passed through the orifice plate. This creates a pressure drop across the orifice plate which varies with the flow rate, resulting in a differential pressure between the outlet and inlet segments.
How does venturi meter work?
A venturi works by measuring the difference in pressure at two different locations. The pressure difference is created by reducing the diameter of the pipe causing the fluid to flow faster. The fast moving fluid has a lower pressure than the slower fluid in the larger section of the venturi.What are the industrial uses of Venturimeter?
Products/Services for Industrial Application Of Venturi Meter. ...the flow rate or quantity of a moving liquid or gas. Industrial processes often require these meters for accurate flow measurements. They allow operators to properly monitor and control process flow and to more easily detect system failures.What is difference between orifice and orifice meter?
In the matter of design, orifice for flow meter always designed to flow in a subsonic velocity in order to ensure the accuracy of flow measurement, while the restriction orifice always designed to flow in the sonic velocity to ensure choked flow. Indeed RO main function is to limit the flow (flow-limiting).How does an orifice control flow?
Orifices, also known as flow restrictors or orifice restrictors, or fixed volumetric flow control, control the flow of gases or fluids through a system. The diameter of these devices maintains a constant flow rate through the system in which it is installed.What is orifice instrumentation?
The Orifice plate is differential pressure flow measurement device. An orifice is simply a smooth disc with a round, sharp-edged inflow aperture and mounting rings.What are the advantages and disadvantages of Orificemeter?
Advantages and disadvantages of orifice plate
- Simple in construction, the standards for construction and calibration are readily available.
- They are cheap; their price does not increase dramatically with size.
- Easy to install and remove.
- They are efficient and reliable for many years.
- Available in many materials.
What are the advantages and limitations of a Venturimeter over Orificemeter?
Advantages of Venturi mater over Orifice meter :Venturi meter is used for operating in-compressible fluids. Venturi meter can handle large range of flow rates of fluid than that of orifice meter. Turn down ratio is 10 : 1. Co-efficient of discharge is relatively high 0.98.
What are the applications of pitot tube?
Pitot tubes are used in anemometers to measure airspeed in wind tunnels and aboard aircraft in flight; they are also used to measure the flow of liquids (see flow meter).What is venturimeter used for Class 11?
Venturimeter is a device to measure the flow of incompressible liquid. It consists of a tube with a broad diameter having a larger cross-sectional area but there is a small constriction in the middle.What is a venturi tube used for?
The Venturi tube or venturimeter is an instrument for measuring with accuracy the flow rate of fluids in pipes.Does a Venturi increase pressure?
A Venturi is a system for speeding the flow of the fluid, by constricting it in a cone shape tube. In the restriction the fluid must increase its velocity reducing its pressure and producing a partial vacuum. As the fluid leave the constriction, its pressure increase back to the ambient or pipe level.How do you calculate Venturi flow rate?
Venturi Flow Equation and Calculator

- and.
- Therefore:
- and.
- Qmass = ρ · Q. Where: Q = volumetric flow rate (m3/s, in3/s) Qmass = Mass flowrate (kg/s, lbs/s) A1 = area = Π · r2 (mm2, in2) A2 = area = Π · r2 (mm2, in2) r1 = radius inlet at A1 (mm, in) r2 = radius inlet at A2 (mm, in)
How do you reduce pressure in a pipe?
Pressure in the pipe can be reduced by following ways:
- Installing pressure relief valves- Can control pipe pressure within range of working of valve.
- Installing diffusers-Can control pressure range for fix value because it has no moving elements.
- Providing Knock-out drums:- Can reduce pressure up to atmospheric pressure.
How does orifice size affect pressure?
A smaller upstream orifice prevents sufficient liquid flow to achieve higher pressure. In these cases, except for the one at the top, a reduction in the size of the nozzle would result in the nozzle spraying a greater distance as the upstream restriction would provide reduced pressure drop because of the reduced flow.How do you reduce water flow rate?
How do you reduce the flow?
- Fit flow restrictors to existing taps and shower mixers. ...
- Fit aerators to kitchen taps. ...
- If you have a very strong shower, have your plumber fit a pressure-limiting valve to reduce flow to the whole plumbing system.
- Replace tap fittings and showerheads with water-efficient fittings.
Where is orifice plate used?
In flow control applications, orifice plates are used as restriction devices to regulate fluid flow or reduce the flowing pressure downstream of the orifice plate. The use of a fixed restriction orifice can be beneficial and economic by reducing the demands on other flow system components.What is orifice plate and venturi?
Orifice has a precisely measured hole in the middle and is inserted in the pipeline to reduce pipe diameter and thereby to offer obstruction. Orifice Plate. Venturimeter consists of a straight inlet section, a converging conical inlet section, a cylindrical throat and a diverging conical outlet section.
