Abstract:The shortage of water resources is common in causing many cities' water demand over its supply,while traditional calculation methods for network are unsatisfactory in results.This paper puts forward a new method of theoretic calculation pondering the random changes of nodal flow being determined by pressures,which can reach solutions with nodal flow and pressure,and computational example are induced showing the correctness and applicability of the method.The new method resolves the problem of hydraulic calculation with unknown nodal flow.
Keywords:water-supply network  water-supply shortages  nodal flow  hydraulic calculation
