A mathematical formulation based on the 1-D NS equations of an unsteady compressible viscous flow in a long one-side closed tube has been presented. The source terms have been estimated on the basis of a solution to the linearized 2-D problem that was obtained earlier. A central spatial discretization and the fourth order Runge-Kutta scheme for time integration have been applied to solve the NS equations. A comparison of outcomes of the model with experimental results for transferring a pressure signal through pneumatic transmission lines has been carried out. Sources of some discrepancies between them have been discussed.
