Question

FULL SCREEN PRINTER VERSION4 BACK Chapter 11, Problem 059 radius of approximately 1.1 cm. The aorta branches eventually into a large numbe tiny capillaries that distribute the blood to the various body organs. In a capillary, the blood speed is approximately o.075 cm/s, and the radius is about 6.7 x 104 cm Treat the blood as an incompressible fluid, and use these data to determine the approximate number of capillaies in the human body Number Units the tolerance is +/-6% Click if you would like to Show Work for this question: Open Show Work SHOW HINT

Explanation / Answer

pi= 3.14
n= pi(1.1 cm)^2 (39 cm/s) = 148.177
n = 148.177 = pi(6.7x10^-4 cm)^2 (0.075 cm/s) (# of capillaries in the blood)
solve for the variable, and you get
14*10^8
