Chapter , Problem 59(choose chapter or problem)
The aorta carries blood away from the heart at a speed of about 40 cm/s and has a radius of approximately 1.1 cm. The aorta branches eventually into a large number of tiny capillaries that distribute the blood to the various body organs. In a capillary, the blood speed is approximately 0.07 cm/s, and the radius is about 6 3 1024 cm. Treat the blood as an incompressible fl uid, and use these data to determine the approximate number of capillaries in the human body.
