The aorta is approximately 25 mm in diameter. the mean pressure there is about 100 mmhg and the blood flows through the aorta at approximately 60 cm/s. suppose that at a certain point a portion of the aorta is blocked so that the cross-sectional area is reduced to 3/4 of its original area. the density of blood is 1060 kg/m3.
(a) how fast is the blood moving just as it enters the blocked portion of the aorta? (in cm/s)
(b) what is the gauge pressure (in mmhg) of the blood just as it has entered the blocked portion of the aorta? (in mmhg)
