Blood flows in an aorta of radius ( 1 mathrm{~cm} ) at ( 30 mathrm{~cm} / mathrm{s} ) 1. What is the volume flow rate? 2. What is the pumping rate of the heart? Give this result in liters per minute. 3. If the aorta reduce its radius to ( 0,5 mathrm{~cm} ) because of thickening of the arterial walls (arteriosclerosis), what is the speed of the blood in the narrower region?

Step 1
To find the volume flow rate, we can use the formula: Volume flow rate = Area × Velocity The area of the aorta can be calculated using the formula for the area of a circle: Area = π × radius² In this case, the radius is 1 cm, so the area is: Area Show more…

The heart of the standard adult pumps 5 liters of blood (with a density of 1030 kg/m3 ) per minute into the aorta: a) What is the volume flow rate (in cm3 /s ) in the cardiovascular system? b) What is the speed of the blood in the aorta given that its diameter is 2.2 cm. c) At some regions of the aorta there is stenosis (due to the deposition of plaque) and the diameter is decreased by 30%. Ignoring the viscosity of blood and assuming laminar flow calculate the speed of blood flow at the stenosis

The flow rate of blood through the average human aorta, with a radius of 1.0 cm, is about 90 cm^3/s. What is the speed of the blood flow through the aorta? (The area of a circle is given by the formula A = πr^2).
