"Compute and gas and liquid orifice plates to measure."
Programs AGA (AGA-3) and ISO (ISO-5167) size, the design requirements for data Plates issued a stream or a flow orifice for the pressure drop to find the pressure drop are given. Standards (AGA-3 (API-2530: 1991) and ISO-5167: 2003) is designed for first gas holes. They are used for liquid orifices in this program.
Programs-types:
- Gas Orifice
- Liquid Orifice
- Restriction Orifice - Gas
- Barring allowed to calculate the following orifice hole - Liquid
gas for gas-specific gravity, temperature and pressure must enter calculations. In addition, N2, CO2 and H2S for sour gas calculations may give mole-fractions.

AGA-8 equation of the Z-Factor (used to calculate the compressibility factor) for natural gas and nitrogen air and Redlich-Kwong equation of state.

---

special oil for the oil weight, temperature and pressure must enter calculations. In addition to molecular weight oil is recommended. Su-entry requirements calculations salinity, temperature and pressure is applied.

---

NOTE: This is all dissolved solids for water expressed as equivalent sodium chloride concentration agree.

---

Results of an orifice for the design of an orifice specification sheet giving the necessary data or an existing hole is evaluated.

---

few factors you should know:
approach is defined as the results will contain the speed factor:

---

Ev = 1 / (sqrt (1-Beta ^ 4))

---

flow, Alpha, is defined as the coefficient:

---

Alpha = Ev * cd

---

and pipe diameter ratio is given as the orifice:
