Based on the graph-theory, ship seawater cooling system fluid network model is built up, and by transforming system single source and single sink network,no source and no sifik network of system is obtained. After analyzing the fluid network flow conservation and loop resistance equations of system node, and using the Quasi-Newton method, the system fluid network calculation is finished, and then, the system network flow distribution characteristics is got. The method used to analyze fluid network based on graphtheory has the property of clear physical concept and high iterative precision. By analyzing the ship seawater cooling system, the effectiveness and reliability is verified, a new practicable method to analyze fluid network is found.
