Using the data and result of Exercise, calculate the pressure difference between the two areas of the aorta. (Blood density: = 1.05 × 10 3 kg/m 3.)
Exercise
The blood flow speed through an aorta with a radius of 1.00 cm is 0.265 m/s. If hardening of the arteries causes the aorta to be constricted to a radius of 0.800 cm, by how much would the blood flow speed increase
