| Summary: | A reliable pipeline design requires hydrodynamic analysis. The analysis enables flow rate and
pressure gradient investigations in obtaining an optimum configuration. On the other hand, a numerical
approach occurs as a complex schematic is proposed. Solving this requirement, an iterative method is
posible to be endorsed. This study aims to investigate single-phase gas pipeline hydrodynamic analysis.
A model utilized a two-phase pressure gradient correlation, namely Beggs-Brill correlation, to converse
single-phase gas pressure gradients into mass flow rates. Furthermore, the numerical method, called
Newton-Raphson, is assesed on solving those iterative calculations. The results show that the model is
able to solve a complex schematic. The mass flow rates obtain in the deviation up to 0.4 %, whereas the
pressure gradients deviation is achieved on a higher value.
