Suppose that blood flows through the aorta with a speed of 0.29 m/s. The cross-sectional area of the aorta is 0.9 10-4 m2.
(a) Find the volume flow rate of the blood.
(b) The aorta branches into tens of thousands of capillaries whose total cross-sectional area is about 2.75 m2. What is the average blood speed through them?
