"The purpose of this study was to investigate crude oil pipeline system once modeled as lumped distributed model and finite element, extracted from initial fluid equations. Substituting actual project values is a way to illustrate the advantages and disadvantages of each model in order to indicate the most effective way of computation. The principal conclusion was indicated that, finite element modeling of lossy pipeline when R and G were included, and 10 km pipeline was divided into five sections, was numerically unstable. Moreover, lossless finite element model required long calculation and high consumption of storage memory. In contrast, an examined study on lossy and lossless transmission line with much shorter computation demonstrated precise and stable transient responses. The result indicated even higher accuracy of lossy system when estimated graph intersects the original graph in three locations."
