ABSTRACT
In water distribution networks, pressure-head at a demand node more than what is required to satisfy the demand is considered as surplus. But, it cannot be completely taken as surplus. Because excess pressure-head at a node is essential to compensate the head-losses in the off-taking links so as to maintain the pressure-head required at downstream nodes. Also, in the recent years, attention is given to avoid too much pressure-heads in order to reduce the damages and leakages in pipes. Thus, there is a need to compute the pressure-head of a node that neither creates pressure-deficit nor too surplus. Such a pressure-head is termed as desirable pressure-head in this paper and a new method to compute it is proposed. The proposed method computes the desirable pressure-head of nodes one-by-one without trial and error. It is easy to adopt and it can be even done for a part of a network.
