The heart pumps blood at an average flow rate of 83.6 cm3/s into the aorta, which has a diameter of 1.5 cm. Determine the average speed of the blood in the aorta.
cm/s
If the diameter of the aorta is reduced to 1.0 cm, but the volumetric flow is the same, what will the new speed of the blood be?
cm/s
