This paper presents a water hammer experiment performed on an artificial blood vessel and the latex tube. Artificial blood vessel was manufactured from latex tubes and textile rubber bands. These bands were wound on outer surface of latex tube and they imitated reinforcing effect of collagen fibres. Mathematical model describes pulsation of pressure after instantaneous closing of valve at outlet of pipeline a part of which is a short elastic tested tube. It is shown that the observed pressure responses can be approximated by a simplified mathematical model assuming linear relationship between internal pressure and inflated volume.
