This paper investigates leak effect on the outlet pressure at pipeline exit. A modified Weymouth equation (includes inclination effect) was used as a governing equation for this study. First, a brief summary of the modified Weymouth equation was reviewed. Next, predicted results by the equation were compared to those by field data for checking discrepancy. Then, to investigate leak effect, outlet pressure and ratio of outlet to inlet pressure were compared between no leak and leak conditions for horizontal, upward, and downward flows, respectively. Finally, effects of leak location as well as leak rate on the outlet pressure were also investigated for all pipeline inclinations.
