Problem: Hardening of the arteries results in a constriction of the arteries. Blood flows with a speed of 26.5 cm/sec through an aorta of radius 1 cm. (Area = 3.14 cm2).
Part A: If the flow of blood is to remain constant, calculate the velocity of blood in a region where the aorta has constricted to a radius of 0.8 cm (Area = 2.01 cm2) due to hardening of the arteries.
Please show all work and steps to determine the velocity of blood in a region.
