5. Calculate the average blood velocity in the major arteries, given that the aorta has a radius of 1.00 cm, the blood velocity is 30.0 cm/s in the aorta, and the total cross-sectional area of the major arteries is 20.0 cm^2. (b) What is the total flow rate in cm^3/s and liters/minute? (c) On the assumption that all the blood in the circulatory system goes through the capillaries, and given that the average velocity of the blood in the capillaries is 3.00 x 10^(-2) cm/s, what is the total cross-sectional area of the capillaries?

1. Compute the decrease in the blood pressure of the blood flowing through an Artery, the radius of which is constricted by a factor of 3. Assume that the average flow velocity in the unconstricted region is 50cm/sec.

At a given instant, the blood pressure in the heart is 1.1 x 104 Pa. If an artery in the brain is 0.38 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow. Number Type your answer here Units Choose your answer here

A flow of (A, = 0.0025m², velocity V, = 7 m/ss) enters a tank. The flow out of the tank exits at a discharge rate (Q = 0. 003 m³ /s). Which of the following statements is correct? dMcV = 11.5 kg/s а. dt b. dMcV – = 12.5 kg/s dt dMCV = 0kg/s %3D С. dt dMcV – 13.5 kg/s d. %3D dt

A- Given that the volumetric flow rate for a fluid within a circular cross-section tube can be represented by Q= πΡΑ ΔΡ 8μL where r is the tube radius, µ is the fluid viscosity, P is the pressure drop across the tube, and L is the tube length, calculate the pressure drop across a tube of length 1 m and diameter of 23 mm. The fluid is blood (μ = 0.0035 N.s/m²) and has a volumetric flow rate of 4.5 L/min. Assuming the same conditions, what would the required pressure drop be for water (μ = 0.001 N.s/m²) and chocolate syrup (μ = 150 N.s/m²).

You are help to educate a patient on the ramifications of a partial arterial blockage you have recently discovered. To communicate the severity, you decide to tell the patient about how much of the volume of blood that normally passes through the artery has decreased. The relationship you are describing is called AV Poiseuille's equation and it reads: ™R^ (P₁-P₂) 8nl If the At radius of the artery decreases by a factor of 2 because of the blockage (as shown in the image below), by what factor has the volume flow rate (A) decreased? At Wall of artery (a) Artery wall thickening Blockage O Note: Do not explicitly include units in your answer, however (include number only). Including units (like cm) will result in the question being scored wrong.

Suppose the flow rate of blood through a 1.9 × 10–6-m radius capillary is 3.65 × 10-9 cm3/s. a.)  What is the speed, in centimeters per second, of the blood flow? (This small speed allows time for diffusion of materials to and from the blood.)  b.) Assuming all the blood in the body passes through capillaries, with the given flow rate in each, how many of them must there be to carry a total flow of 90.0 cm3/s?

A hydraulic has two pistons. The area of piston 1 is ELEVEN times SMALLER than the area of piston 2. If a pressure of 96 atm is applied to piston 1, how much pressure will piston 2 experience as a result? Express your answer in atm.
