This paper presents an iterative calculation method of computing node pressures and consumptions at all nodes in steady-state pipeline networks by means of a node admittance matrix which is used as an analytical method for topological electrical networks. This method has advantages in that the topological characteristics of the networks are automatically recognized when the node admittance matrix is established according to a simple rule, and the convergence of iterative calculation is always atteained in a wide range of initial values. This paper shows that introduction of a relaxation factor is effective in successfully attaining the convergence. The influence of the relaxation factor on the convergence is also discussed and the practical range of the factor is recommended. The comparison of computed results between the traditional Hardy-Cross method and the method presented herein shows good agreement.
