Find step-by-step Physics solutions and your answer to the following textbook question: If the velocity of blood flow in the aorta is normally about $0.32$ m/s, what beat frequency would you expect if $5.50$-$\mathrm{MHz}$ ultrasound waves were directed along the flow and reflected from the red blood cells? The reason for these differences in blood flow velocity is wall stress (a type of shear stress). When a fluid, in this case, blood, flows through a pipe, friction exists between the fluid and the wall of the tube. This friction decreases the velocity of the blood closest to the wall (hence the shorter lines on the diagram closer to the tube wall). we want the velocity blood flow in capillaries to be slow.
