Where do you find the AC orifice tube on a 2001 Chevrolet venture van?

It does not have an orifice tube.


How does a restriction orifice in a pipe work?

the orifice plate creates a restriction in the pipeline which creates a pressure drop across the plate. commonly found in high pressure relief systems or drain points (as this would usually be a HP/LP interface) and can also be used to measure flow, by measuring the pressure drop across the plate.


What is nozzle pressure?

Pressure build up due to restricted orifice.


Difference between an orifice plate and a restriction orifice?

An orifice plate is a plat eused to measure flow. Pressure sensors are placed upstream and downstream of the the plate and hepressure differential is used with Bernoullis Equation t compute flow (including some experimental factors). A retriction plate is similar to an orifice plate but is much thicker. It is used to drop pressure upstream of a system. The convergence, throttlnig through thick section and divergece works the fluid and reduces total energy (transformed in firction, heat etc). This leads to an overall pressure reduction.


What is depth of orifice?

An "orifice" is a word for a hole (usually a hole in an animal's body". Therefore the "depth of an orifice" would be a measure of the length from the hole opening to the closed end.


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.


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.


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.


Applications of orifice meter?
