When capillaries are larger in diameter the speed of blood flowing through them changes. In what way is the flow speed changed?

When measuring blood pressure, why is the cuff placed at the level of the heart? Would the blood pressure reading change if it were taken at the proximal thigh? Why? Your answer should include a discussion on what factors determine the pressure of a fluid.

Is it possible for a fluid in a tube to flow in the direction from low pressure to high pressure? If so, give an example. If not, why not?

A pipe with a cross section area of 0.5 m^2 has a fluid flowing through it at a speed of 2m/s. If the pipe’s cross section area is reduced to 0.25 m^2, what is the speed of the fluid in the reduced section?

Question 8 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 fınds that it is 1.20 × 104 Pa, while in the region of the 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 specific gravity of this patient blood is 1.06. What percentage of the cross-sectional area of the patient's artery is blocked by the plaque? (NO NEED TO PUT PERCENT SYMBOL).

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 × 10^4 Pa, while in the region of blockage it is 1.15 × 10^4 Pa. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is traveling at 30 cm/s, and the density of this patient’s blood is 1.06 × 10^3 kg/m^3. What percentage of the cross-sectional area of the patient’s artery is blocked by the plaque? Assume that gravity has negligible effect on the flow of blood.

Consider a cube of wood.  The cube of wood floats in a fluid so that half of its volume is submerged. What is the Sumbmerged Fraction?

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 P₁, while in the region of blockage it is P2. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is traveling at v₁, and the density of this patient's blood is p. The patient is laying down so there are no differential effects due to gravity. a. Symbolically, what is the ratio of the artery radius at the blockage, r2, to the ratio of the artery radius at the blockage, r₁? (find r₂/r₁) b. Find the numerical value of r2/r1. P₁ = 1.20x104 Pa, P₂=1.15×104 Pa, v₁ =30.0 cm/s, p = 1060 kg/m³.

1. (a) A kitchen sink has a volume of 15 L. If the drain is closed and the sink is initially empty, plot the volume of water in the sink as a function of time. How long will it take to overflow the sink after the faucet is open, allowing a flow rate of 0.3 L/min?
