Suppose blood flows through a 1 cm diameter vessel at .6 m/s. Suddenly, through sphincter constriction the diameter of the vessel is reduced to .5 cm. Assuming the volume flow rate is unchanged (i.e. continuity holds):
a) Will there be noise associated with the initial unconstricted flow? (5 pts) b) Will there be noise associated with the final constricted flow? (5 pts)
The Reynold’s Number for blood is 1000, the viscosity of blood is .004 Pa-s, its density is the same .Hint: Here you need to apply the continuity equation and investigate both diameters to see if vc is exceeded in either one.
