The volumetric flow rate of blood in a person at rest is about 5 L per minute. The beginning of the aorta (the part closest to the heart) has a diameter of 3 cm, but the end of the aorta in the lower abdomen has a diameter of only 1.75 cm. a. What is the flow rate of blood at the beginning of the aorta in m/s? b. What is the flow rate of blood at the end of the aorta in the lower abdomen in m/s? c. How much faster is the blood traveling at the end of the aorta than it is at the beginning?
