Vol. 7, No. 4, 2019, pp. 95-102. doi: 10.11648/j.ogce.20190704.12http://hdl.handle.net/123456789/1453Mathematical model for leak location in natural gas pipeline has been developed in this paper. The model employs an isothermal steady state approach. Leak occurrence in the pipeline divides the pipeline into two sections-the upstream and downstream sections respectively. Analyses of leak incidences were carried out in the two pipeline sections giving rise to two equations being developed to address the leak localization. The first leak equation was developed by considering the upstream section of the pipeline while the second leak equation was developed by considering the downstream section of the pipeline. The two equations were analytically developed by slight modification of the Weymouth’s equation for gas flow in horizontal pipeline. Matlab software was used in the model simulation.enLeak Location,Mathematical ModelUpstream SectionDownstream SectionArticle
