Chapter 14, Problem 24P

* BIO Flutter in blood vessel A person has a ${\text{5200-N/m}}^{\text{2}}$ gauge pressure of blood flowing at 0.50 m/s inside a 1.0-cm-radius main artery. The gauge pressure outside the artery is ${\text{3200 N/m}}^{\text{2}}$. When using his stethoscope, a physician hears a fluttering sound farther along the artery. The sound is a sign that the artery is vibrating open and closed, which indicates that there must be a constriction in the artery that has reduced its radius and subsequently reduced the internal blood pressure to less than the external ${\text{3200 N/m}}^{\text{2}}$. pressure What is the maximum artery radius at this constriction?
