Challenge Problem: An aneurysm is an abnormal enlargement of a blood vessel such as the aorta. Because of an aneurysm, the cross-sectional area of the aorta increases by 1.7 times. The speed of the blood (ρ = 1060 kg/m3) through a normal portion of the aorta is 0.40 m/s. Assuming that the aorta is horizontal (the person is lying down), determine the amount by which the pressure P2 in the enlarged region exceeds the pressure P1 in the normal region.
