Short summary
This paper presents a simple methodology for assessing the supplying capacity of demand nodes under pressure-deficient conditions by assigning the respective emitter coefficient only to those nodes facing the pressure-deficit condition. Though the proposed approach follows an iterative methodology using EPANET software, the computational burden of adding artificial elements to the other methods is avoided and is hence useful for analyzing large networks.
