Summary

This paper deals with propagation of pulse wave in viscoelastic tube, with viscose liquid inside. Fundamental partial differential equations describing pulse wave were derived. Further, formulas for phase velocity and damping of wave were derived. Propagation of wave through dividing line between two mechanically different parts of tube was also analyzed. Formulas for reflections and passage were derived.
