Wall Shear Stress and Pressure: The average blood velocity through an internal carotid artery with a diameter ? = ? mm during resting conditions was measured to be ? = ?? cm/s. Assuming Poiseuille flow through the arterial segment and a viscosity coefficient of ? = 3.5 cP for whole blood, determine the following: a) The shear stress ? that the endothelial cells in the artery are being subjected to. b) The average pressure gradient ∆?/? required to maintain steady flow at ? = ?? cm/s.
