A garden hose with an internal diameter of 1.3 cm is connected to a (stationary) lawn sprinkler that consists merely of a container with 27 holes, each 0.12 cm in diameter. If the water in the hose has a speed of 0.91 m/s, at what speed does it leave the sprinkler holes? Number Units Blood flow. The cross-sectional area Ao of the aorta (the major blood vessel emerging from the heart) of a normal person is 2.64 cm and the speed vo of the blood is 29.1 cm/s. A typical capillary (diameter 6 m) has a cross-sectional area A of 3.21 10-7 cm and a flow speed v of 0.070 cm/s. How many capillaries does such a person have? Number Units
