Abstract
In the development of formulas for oscillatory flow in rigid and elastic tubes which have been used to predict arterial flow, the question arises as to whether it is justifiable to assume that blood may be treated as a homogeneous liquid of constant viscosity. Equations of motion are derived for the hypothetical case in which the viscous drag of the liquid is composed of 2 parts, one proportional to the velocity gradient and the other proportional to its time derivative.
