If the density of blood is
1060 kg/m3 and the blood rose 2 m in Hales experiment on
blood pressure in a hourse, what was the arterial blood pressure
(gauge) in kPa and mmHg, where 7.5 mm Hg = 1 kPa and 1 Pa = 1
N/m2 ( 1 N = 1 kg m/s2 )
The buildup of plaque on the walls of an artery may decrease its diameter from 1.1 cm to 0.71 cm. The speed of blood flow was 14 cm/s before reaching the region of plaque buildup. (a) Find the speed of blood flow within the plaque region. cm/s (b) Find the pressure drop within the plaque region. (Assume the density of blood is 1060 kg/m3.) Pa
Water (density = 1.0 x 103 kg/m3 ) flows through a horizontal tapered pipe. At the wide end its speed is 4.0 m/s. The difference in pressure between the two ends is 4.5 x103 Pa. The speed of the water at the narrow end is: A. 2.6 m/s B. 3.2 m/s C. 4.0 m/s D. 4.5 m/s E. 5.0 m/s
Focus on Concepts, Question 17 Try again. The change in pressure is incorrect. Blood flows through a section of a horizontal artery that is partially blocked by a deposit along the artery wall. As a hemoglobin molecule moves from the narrow region into the wider region, speed changes from vy-0.800m/s tovy -0.374 m/s. What is the change in pressure, that it experiences? The density of blood is 1060kg/ml Depot 245.708 the tolerance is +/-29

12 Calculate the hydrostatic difference in blood pressure between the brain and the foot in a person of height 1.8 m. The density of blood is 1060 kg/m3. Ignore any pressure changes due to blood flow. A) 18.7 kPa B) 48.7 kPa C) 123 kPa D) 37 kPa
Plaque builds up on the walls of an artery decreasing its diameter from 1.16 cm to 0.70 cm. If the flow speed is 14.5 cm/s before reaching the region of plaque buildup, determine the following. (a) speed at which blood is traveling through the plaque-constricted region cm/s (b) pressure change within the plaque-constricted region. (Assume the density of blood is 1050 kg/m3. Be sure to include the appropriate sign with your answer.) Pa
Blood flows through a section
of a horizontal artery that is partially blocked by a deposit along
the artery wall. What is the speed of the blood in the partially
blocked region?
Focus on Concepts, Question 15 Blood flows through a section of a horizontal artery that is partially blocked by a deposit along the artery wall. What is the speed of the blood in the partially blocked region? Deposit 72 = 2.0 mm 1.0 mm v2 = 0.40 m/s...
Arteriosclerotic plaques forming on the inner walls of arteries can decrease the effective cross-sectional area of an artery. Even small changes in the effective area of an artery can lead to very large changes in the blood pressure in the artery and possibly to the collapse of the blood vessel.Imagine a healthy artery, with blood flow velocity ofv0=0.14m/s and mass per unit volume ofρ=1050kg/m3. The kinetic energy per unit volume of blood is given byK0=12ρv20.Imagine that plaque has narrowed an...
·A medical technician is trying to determine what percentage of a patient's artery is blocked by plaque. To do this, she measures the blood pressure just before the region of blockage and finds that it is 1.20 x 10 4 Pa, while in the region of blockage it is 1.15 x 104 Pa. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is traveling at 30.0 cm/s, and the density of this patient's...
Jeff's body contains about 4.59 L of blood that has a density of 1060 kg/m3. Approximately 45.0% (by mass) of the blood is cells and the rest is plasma. The density of blood cells is approximately 1125 kg/m3, and about 1% of the cells are white blood cells, the rest being red blood cells. The red blood cells are about 7.50?m across (modeled as spheres). What is the mass of the blood ?blood in Jeff's body? ?blood= 4.87 kg Approximately...
