A patient has an axisymmetric constriction (stenosis) in an artery near the heart due to plaque buildup. a.) Given that the velocity upstream of the constriction is 24 cm/s during systole and 10 cm/s during diastole, calculate the maximum and minimum velocity at the stenosis (10 points) (Dont overthink this one!) b.) Could the conservation of mass equation be used to find the shear stress profile of fluid flowing through the stenosis? Please explain briefly why or why not. (5 points)
