Is there an equation that addresses how pressure psi affects flow cfm through a fixed orifice?
yes, the pressure is directly related to the effective force acting on the fluid body, so from the pressure differential you can compute the effective force on a small mass of fluid in the orifice, which can then be translated into a flux integral, which can be solved for Volume/time.

What is nozzle pressure?
Pressure build up due to restricted orifice.
How does an orifice affect flow and pressure?
An orifice is a small opening that restricts flow in a fluid system, leading to a decrease in pressure as the fluid passes through. According to Bernoulli's principle, when fluid velocity increases as it flows through the orifice, the pressure drops. This pressure drop can create a differential pressure that can be used for measurement or control in various applications. Additionally, the size and shape of the orifice can significantly influence the flow rate and behavior of the fluid.

How do you calculate Orifice plate differential pressure?
To calculate the orifice plate differential pressure, you can use the Bernoulli's equation or the ISO 5167 standard equation. Measure the pressure upstream and downstream of the orifice plate using pressure gauges, then find the difference between these two pressures to determine the differential pressure across the orifice plate.
How orifice meter can measure a preasre?
Orifice meter measures pressure by forcing fluid through a restriction (orifice plate) in the pipeline, causing a pressure drop. This pressure drop is proportional to the flow rate, which can be used to determine the pressure of the fluid. By measuring this pressure drop, the orifice meter can indirectly measure the pressure of the fluid in the pipeline.
What can you say definitely about the pressure about the opposite sides of an orifice when oil is flowing through it?
When oil flows through an orifice, the pressure on the upstream side (before the orifice) is typically higher than the pressure on the downstream side (after the orifice). This pressure difference is necessary to overcome the resistance to flow caused by the orifice's size and shape. As oil passes through the orifice, it accelerates, resulting in a decrease in pressure on the downstream side according to Bernoulli's principle. Therefore, the pressure on the upstream side will always be greater than the pressure on the downstream side during flow.
How do you calculate steam flow through orifice?
To calculate steam flow through an orifice, you can use the orifice flow equation: [ Q = C_d A \sqrt{\frac{2 \Delta P}{\rho}} ] where ( Q ) is the volumetric flow rate, ( C_d ) is the discharge coefficient, ( A ) is the orifice area, ( \Delta P ) is the pressure drop across the orifice, and ( \rho ) is the density of the steam. First, determine the orifice area based on its diameter, measure the pressure drop, and then use steam tables to find the density of the steam at the given conditions to compute the flow rate.

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.

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.
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.
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.
How does an orifice meter work to measure fluid flow rate?
An orifice meter works by measuring the pressure difference created when fluid flows through a small opening called an orifice plate. This pressure difference is used to calculate the flow rate of the fluid passing through the meter.
