Suppose blood is pumped from the heart at a rate of 4.9 L/min into the aorta of radius 1.1 cm. Determine the speed of blood through the aorta, in centimeters per second.

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.

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

Suppose blood is pumped from the heart at a rate of 4.5 L/min into the aorta of radius 1.2 cm. Determine the speed of blood through the aorta, in centimeters per second. V?

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.

In the process of loading a ship, a shipping container gets dropped into the water and sinks to the bottom of the harbor. Salvage experts plan to recover the container by attaching a spherical balloon to the container and inflating it with air pumped down from the surface. The dimensions of the container are 5.00 m long, 2.35 m wide, and 3.20 m high. As the crew pumps air into the balloon, its spherical shape increases and when the radius is 1.10 m, the shipping container just begins to rise toward the surface. Determine the mass of the container. You may ignore the weight of the balloon and the air in the balloon. The density of seawater is 1027 kg/m³. 434.54 X How does the weight of the container compare to the weight of the water displaced by the container and balloon when the container starts to rise? See if you can express the weight of the water displaced in terms of the density of the seawater and the dimensions of the container and balloon. kg Additional Materials

A bottle with a volume of 181 U. S. fluid gallons is filled at the rate of 1.6 g/min. (Water has a density of 1000 kg/m3, and 1 U.S. fluid gallon = 231 in.3.) How long does the filling take?

The average speed of blood in the aorta is 0.330 m/s, and the radius of the aorta is 1.00 cm. There are about 2.00 × 109 capillaries with an average radius of 6.19 μm. What is the approximate average speed of the blood flow in the capillaries?   ?mm/s

Suppose blood is pumped from the heart at a rate of 4.6 L/min into the aorta of radius 1.1 cm. -Determine the speed of blood through the aorta, in centimeters per second. (v= )

A cylindrical blood vessel is partially blocked by the buildup of plaque. At one point, the plaque decreases the diameter of the vessel by 70.0%. The blood approaching the blocked portion has speed ?0. Just as the blood enters the blocked portion of the vessel, what is its speed ?, expressed as a multiple of ?0? ?=   × ?0
