- Suppose a blood vessel’s radius is decreased to 88 % of its original value by plaque deposits and the body compensates by increasing the pressure difference along the vessel to keep the flow rate constant. a. By what factor must the pressure difference increase?9. The blood speed in a normal segment of a horizontal artery is 0.12 m/s. An abnormal segment of the artery is narrowed by an arteriosclerotic plaque down to one-third its normal cross-sectional area. What is the difference in blood pressures between the normal and constricted segments of the artery? (The density of the blood is 1060 kg/m3) Pa1. Suppose a person is 182 cm tall. A typical blood pressure is often given as 110/70 mm Hg, with a mean pressure of 80 mm Hg. A. Do you think this is the gauge pressure or absolute pressure? Why? If the pressure at the top of the head is about 39 mm Hg, how far away is this person's head from the heart? Assume the density of blood is about 6% higher than that of water. t, What then would be the blood pressure.of this 6, person at their feet? b. Suppose this person suffers a puncture wound around the same height as the heart where the opening is about 3 mm in diameter. How far could blood shoot from their body assuming it comes out horizontally with 0 m/s initial horizontal velocity? %3D = 0.754 Since horizontal velocity is zero it will not go eny for than body Please explain the variábles used in the equation to solve for F= P.A in partad of this question.
