1. Consider an artery with parameters a=D.4cm, = 40cmfs, ,u = 3 x 10'3stm2, p = lkyfm? Estimate the Reynolds number, Re, and what kind of flow, laminar or turbulent, is expected in this vessel. 2. Consider an area of stenosis in a cylindrical vessel. Assume that the diameter of the stenotic area is a half of that in the vessel. What is the pressure change in stenotic area that provides the same volumetric flow rate as in the vessel away from the stenotic area? 3. Consider ex vivo perfusion system. Assuming a fully developed laminar flow where a=2.2 mm and y. = 4 CF, find the value of the volumetric flow rate providing a physiologic wall shear stress of 1.5Pa
