Problem 7. (The speed of blood) The aorta (the main blood vessel coming out of the heart) has a radius of about 1.0 cm and the total cross section of the major arteries is about 20 cm². The density of blood is 1.05 g/cm3. A. Given that the velocity of blood pumping through the aorta is about 48 cm/s, what is the total current of the blood passing through the aorta (in grams of blood per second)? B. If all...

A liquid_p = 1.45 g/cm^2) flows through a horizontal pipe of varying cross section as in the figure below. In the first section, the cross-sectional area is 10.0 cm^2, the flow speed is 248 cm/s, and the pressure is 1.20 times 10^5 Pa. In the second section, the cross-sectional area is 4.50 cm^2. Calculate the smaller section's flow speed. (Enter your answer to at least two decimal places.) m/s Calculate the smaller section's pressure. Pa Whole blood has a surface...
Compared to normal blood flow velocity, v0, what is the velocity of blood as it passes through this blockage?
Arteriosclerotic plaques forming on the inner walls of arteries can decrease the effective cross-sectional area of an artery. Even small changes in the effective area of an artery can lead to very large changes in the blood pressure in the artery and possibly to the collapse of the blood vessel.Imagine a healthy artery, with blood flow velocity ofv0=0.14m/s and mass per unit volume ofρ=1050kg/m3. The kinetic energy per unit volume of blood is given byK0=12ρv20.Imagine that plaque has narrowed an...

Blood flows in an aorta of radius 4.38mm at 32.5cm/s. a) Calculate the volume flow rate. b)Although the cross-sectional area of a capillary is much smaller than that of the aorta, there are many capillaries, so their total cross-sectional area is much larger. If all the blood from the aorta flows into the capillaries and the speed of flow through the capillaries is 1.10mm/s, calculate the total cross-sectional area of the capillaries.

Blood flows in an aorta of radius 4.12mm at 32.5cm/s. Calculate the volume flow rate. Tries 0/10 Although the cross-sectional area of a capillary is much smaller than that of the aorta, there are many capillaries, so their total cross-sectional area is much larger. If all the blood from the aorta flows into the capillaries and the speed of flow through the capillaries is 0.85mm/s, calculate the total cross-sectional area of the capillaries.
