An aneurysm is an abnormal enlargement of a blood vessel such as the aorta. Because of an aneurysm, the normal cross-sectional area A1 of the aorta increases to a value of A2 = 1.7A1. The speed of the blood through a normal portion of the aorta is v1 =0.26 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.
