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.
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 orifice meter?
hitler
What is the plural form of the word orifice?
Actually, orifices.
What is the function of a speculum?
Opening a body orifice or cavity for viewing
Orifice in a sentence?
By the time the fight was over, the boxer had blood flowing from every orifice of his broken body.
What is the working principle of orifice meter?
An obstruction (orifice) is placed in a pipe filled with fluid. The pressure of the fluid is measured at two different points: 1) just upstream of the orifice and, 2) close to the contraction of the fluid (vena contracta). The difference in these two pressures is known as differential pressure. The differential pressure across an obstruction (orifice) in a pipe of fluid is proportional to the square of the velocity of the fluid. Many factors associated with the pipe, orifice and fluid affect the measurement. Satisfactory measurement requires steady-state, homogeneous, turbulent flowing fluids. Other properties which affect the measurement include: the ratio of pipe diameter to orifice diameter and the density, temperature, compressibility and viscosity of the fluid.
Can you get negative answer for orifice meter?
Yes. The fluid may be flowing backwards or there may be obstructions or distortions in the pressure-sensing lines between the primary measurement device and the secondary measurement device.
What is nozzle pressure?
Pressure build up due to restricted orifice.
What is the difference between Restriction Orifice and Flow orifice or please explain the symbols RO Restriction orifice and FO Flow Orifice?
A restriction orifice (RO) is used to limit the flow through the pipe to a set flow by choking the flow at its sonic velocity. A flow orifice (FO) is usually used to determine the flow through the pipe from the pressure drop over the plate. There a normally two pressure taps (one on each side of the plate) and a pressure transmitter which determines the pressure drop over the plate. A formula is then used to convert this pressure drop to a flowrate for the specific fluid passing through the orifice. A FO usually has a temperature element to determine the gas temperature for use is the formula.
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.
Why is wheezing usauly worse when asthmatics exhale?
exhaling causes negative pressure in the airways of the lung structure. the weakened muscular wall of the airway responds to this negative pressure by collapsing inward narrowing the airway. result is air flowing through a smaller orifice creating a wheezing sound.
Where is the ac low pressure side switch on 4.3 Blazer?
It's not a switch. The high pressure runs from the compressor outlet to the orifice tube inlet, and the low pressure side runs from the orifice tube outlet to the compressor inlet.
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.
What would stop freon from flowing into the low pressure port during a needed recharge-the clutch is engaged on the compressor and the max air is on-gauge shows low pressure but freon won't flow?
If the clutch is engaged & turning, there should be no problem getting freon into the system, unless the orifice tube is plugged.
Can an orifice in a steam line act as a steam pressure reducing valve?
Yes. But it is limited in control by the orifice size, pressure applied and piping diameter. In other words it is "fixed". An example would be the metering device in a refrigerant circuit, specifically an orifice or capillary tube. The same physics apply.
Where is the orifice filter located on a 98 escort zx2?
in the high pressure line
