In an aortic aneurysm, a bulge forms where the walls of the aortaare weakened. If blood flowing through the aorta (radius 1.0 cm)enters an aneurysm with a radius of 3.0 cm, how much on average is the blood pressure higher inside the aneurysm than the pressure inthe unenlarged part of the aorta? The average flow rate through theaorta is 120 cm3/s. Assume the blood is nonviscous and the patientis lying down so there is no change in height.
