This paper investigates leak effect on the outlet pressure at pipeline exit. A modified Weymouth equation(including inclination effect) was used for this study. 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. Then, effects of leak location as well as leak rate on the outlet pressure were also investigated for all pipeline inclinations.
