Gas Flow Rate and Maximum Gas Rate in Pipelines

The gas flow rate depends on various factors, including pipe dimensions, gas properties, and pipeline design parameters. Different equations are used to estimate gas flow rates under different conditions. Designing a long-distance pipeline for transportation of natural gas requires knowledge of fluid flow in pipeline (calculating flow capacity & pressure).

In gas transportation pipelines, the gas compressibility factor depends on pressure and the friction factor depends on flow rate which affects the pressure drop through the pipeline. Several correlations are developed to estimate gas flow capacity through pipelines considering these effects.
