Abstract: This paper presents a node pressure model of network steady-state analysis dealing with elevation difference and friction coefficient. The introduction of pseudo-Newton iteration method for non-linear algebraic equations increases the analysis convergence, and allows a wider range of iteration initial value. An example is given in this paper. Not only an improved model is given,but also an effective solution is suggested.
