An Overview of Gas Flow Measurement
Gas distribution metering requires accurate flow measurement because diverse applications may require varying volumes of gas Gas distribution metering. Many chemical processes require large varying volumes of specific gases, such as nitrogen, argon and oxygen for inert ions or purging or blanketing.
excel spreadsheet for natural gas pipeline flow calculations
Natural Gas Pipeline Flow Calculation Spreadsheet. If the pressure drop across the pipe is less than 40 % of the average pipeline pressure, then the Darcy Weisbach equation is a possibility. For longer pipelines with larger pressure drop, the three equations that are in most common use are the Weymouth equation, the Panhandle A equation,
Compressible gas flow
Pipe flow rate, pressure and friction factor in isothermal compressible gas flow The flow in long pipelines closely approximates isothermal conditions. The pressure drop in such lines is often large compared to inlet pressure and solution of this problem is outside the limitations of the Darcy equation.
Compressible gas flow
In the case of the gas compressible flow through a short pipe into the area with larger cross section, or into the atmosphere, the flow is usually considered to be adiabatic. For this situation Darcy formula should be used with factors to compensate on the fluid changes due to expansion, using expansion factor Y. Modified Darcy formula with expansion factor included is then:
Orifice plate Wikipedia
An orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow. Either a volumetric or mass flow rate may be determined, depending on the calculation associated with the orifice plate. It uses the same principle as a Venturi nozzle, namely Bernoulli's principle which states that there is a relationship between the pressure of the fluid and the velocity of the fluid. When the

Gas Flow Patterns. Gas flow patterns are of greatest importance for growth of films with uniform thickness and composition, particularly at ‘high’ pressures (about 1 atm). The diffusivity of the vapor species increases at reduced pressures, which results in better mixing of the process gases, and hence the flow fields become less important.

Gas Flow Rate for MIG?
Gas flow depends on the size of the nozzle. For the smaller 1/2" size nozzles you want generally 15 20 cf/hr. For the larger 3/4" size nozzles you run about 25 40 cf/hr. I tend to prefer the large nozzles since they provide a lot better gas coverage. If you turn the gas flow up too high you create a turbulent gas flow.
