Chapter 5, Problem 25P

The area of the aortic valve, A_Vin cm², can be estimated by the equation (Hakki Formula):

$A_V=\frac{Q}{\sqrt{PG}}$

whereQ is the cardiac output in L/mim, and PG is the difference between the left ventricular systolic pressure and the aortic systolic pressure (in mm Hg). Make one plot with two curves of A_Vversus PG, for $2\le PG\le 60\text{mm}$ Hg— one curve for Q = 4 L/mim and the other for Q = 5 L/min. Label the axes and use a legend.
