For what purpose would one use an orifice meter?
The orifice meter is used with the orifice flow rate meter and measures things like the flow rate of natural gas. It can measure other things and companies use it for different things also. Some companies give lessons or classes in using the orifice meter.
Who invented the meter of length?
Meter as a unit of length was not invented but introduced in accordance with international convention, in 1875. The idea of introducing the metric system originated in France in the 18th century.
What is the plural form of the word orifice?
Actually, orifices.
Is coefficient of discharge constant?
No coefficient of discharge is not constant. It is a function of many parameters like :The ratio of the length of the orifice to diameter of orificeReynolds numberflow condition-whether it is increasing or decreasingPressure at the exit of the orifice (back pressure)Orifice entry condition- like smooth entry, sharp edged entry etc.
What is the function of a speculum?
Opening a body orifice or cavity for viewing

Advantage and disadvantage of orifice meter?

What is orifice meter?
Orifice meter is a flow measuring device used for calculating the pressure drop,flow rate and behaviour of the fluid moving through the pipe.
What is the calibration curve of orifice meter?
The calibration curve for an orifice meter will depend on the size of the orifice, the size of the pipe and the pressure loss over the meter. Typical calibration curves have pressure (or head) loss on the vertical (y) axis and flow rate on the horizontal (x) axis.
Why Cd value is high in nozzle meter than orifice meter?
more accurate
Why is coefficient of discharge of venturi meter is more than coefficient of discharge of orifice meter?
In Venturi meter losses are less so coefficient of discharge is higher whereas in orifice meter due to no convergent and divergent cones there are more losses and hence its coefficient of discharge is less.In venturi meter losses are low due to steamline shape of the diffuser and the pressure gradient is not abrupt as in case of orifice meter.
What is the order of efficiency of venturi meter orifice meter and rotoameter?
The orifice plate can easily be changed to accomodate widely different flow rates, whereas the throat diameter of a venturi is fixed, so that its range of flow rates is circumscribed by the practical limits of Dp.The orifice meter has a large permanent loss of pressure because of the presence of eddies on the downstream side of the orifice-plate; the shape of the venturi meter prevents the formation OS these eddies and greatly reduces the permanent loss.The orifice is cheap and easy to install. The venturi meter is expensive, as it must be carefully proportioned and fabricated. A home made orifice is often entirely satisfactory, whereas a venturi meter is practically always purchased from an instrument dealer.On the other hand, the head lost in the orifice for the same conditions as in the venturi is many times greater. The power lost is proportionally greater, and, when an orifice is inserted in a line carrying fluid continuously over long periods of time, the cost of the power may be out of all proportion to the saving in first cost. Orifices are therefore best used for testing purposes or other cases where the power lost is not a factor, as in steam lines.However, in spite of considerations of power loss, orifices are widely used, partly because of their greater flexibility, because installing a new orifice plate with a different opening is a simpler matter. The venturi meter can not be so altered. Venturi meters are used only for permanent installations.It should be noted that for a given pipe diameter and a given diameter of orifice opening or venturi throat, the reading of the venturi meter for a given velocity is to the reading of the orifice as (0.61/0.98)2, or 1:2.58.(i.e. orifice meter will show higher manometer reading for a given velocity than venturi meter).
Applications of orifice meter?
1.to measure the flow rate of gases and fluids
Why did Hitler invent an orifice meter?
He didn't invent it. He didn't invent anything.
How do I compute volume of airflow?
orifice meter is used for measuring volume flow rate air.
Applications of orifice meter in industries?
(to check the flow rate of water ... calculate the pressure drop
Why is the orifice plate called a variable head flow meter?
Because it relies on the back pressure through a known orifice which its differential pressure across the plate relates to flow.
