The drawing shows an intravenous feeding With the distance shown, nutrient solution (.0 = 1050 kgfmal can just barely enter the blood in the vein. What is the gauge pressure of the venous blood? Express your answer in millimeters of mercury. atmospheric pres\": :r 0.510 rn Number I Units V 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 = 1.71% . The speed of the blood (,0 = 1060 kg/m3] through a normal portion of the aorta is v1 = 0.44 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. III A _ .
