70 percent

Work Step by Step

We adjust the equation found in example 15.7 to find: $\frac{A_2}{A_1}=\sqrt{\frac{2\Delta P}{\rho (v_1)^2}+1}$ $\frac{A_2}{A_1}=\sqrt{\frac{2(.05)(10,000)}{(1060) (.3)^2}+1}=3.39$ Thus, we find how much is not obstructed: $\frac{1}{3.39}=.295=29.5$% Thus, 70% of the artery is obstructed.
