The aorta is approximately 25 mm in diameter. The mean pressure there is about 100 mmHg, and the blood flows through the aorta at approximately 60 cm/s. Suppose that at a certain point a portion of the aorta is blocked so that the cross‑sectional area is reduced to 1/3 of its original area. The density of blood is 1060 kg/m3. (a) How fast v ( in cm/s) is the blood moving just as it enters the blocked portion of the...
Compared to normal blood flow velocity, v0, what is the velocity of blood as it passes through this blockage?
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...

Question 1 The cylindrical pressure vessel shown has an inside diameter of 625 mm and a wall thickness of 5 mm. The cylinder is made of an aluminum alloy that has an elastic modulus of E = 70 GPa and a shear modulus of G-26.3 GPa. Two strain gages are mounted on the exterior surface of the cylinder at right angles to each other; however, the angle θ is not known. If the strains measured by the two gages are...

BLOOD AND FLUID QUESTION 1 (0A patient's blood pressure taken at the arm is 120 mmHg systolic and 70 mmHg diastolic. What would you expect the blood pressure (systolic and diastolic pressures) to be at the top of the head given that this point is 40 cm above the measurement point? Remember blood pressure is a gauge pressure and that 1 kPa = 7.5 mmHg. (The density of blood is about 1060 kg/m.) Choose one: a. 89...

Two red blood cells each have a mass of 9.05 x 10-14 kg and carry a negative charge spread uniformly over their surfaces The repulsion arising from the excess charge prevents the cells from clumping together. One cell carries -2.10 pC and the other 2.60 pc, and each cell can be modeled as a sphere 3.75 × 10-6 m in radius. If the red blood cells start very far apart and move directly toward each other with the same speed,...
