..., among others, more than half a century ago. However, pipe manufacturing and treatment methods have become more advanced since these studies were performed. Indeed, recent studies have suggested overestimation of the pressure drop across a pipeline during design resulting in less accurate cost estimates...

... drop in pressure creates a pressure wave that propagates along the pipeline. Compressor stations integrate a selection of safety systems and practices, including automatic shut- down systems. These systems can detect abnormal conditions such as unanticipated pressure drops and pipeline leaks...

... to represent the flow network. For example, the impact of pressure drops caused by a bend, tee or reduction is much greater on a valve manifold than on a transcontinental pipeline, thus it is important to adopt the modeling methodology to the system scale. In addition, to accurately represent a liquid system...
