The mathematical modeling of a gas network is a powerful tool in order to identify the behavior of system under the different conditions. The modeling can be performed both for the steady state and unsteady state conditions. It is possible to use the fluid flow basic governing equations or the electrical analogy concept for developing the model. The second approach provides a simpler and more robust model, especially in large networks with different and numerous components. In this study this approach has been used for studying the steady state behavior of a sample gas distribution network. The model is verified by comparing its results with some existing experimental and numerical data. The comparison shows a very good agreement between the two results.
