Variation of pressure

From the equation of pressure, pressure is directly proportional to the applied force.

Question

**Balloon Angioplasty**

Balloon angioplasty is a medical procedure used to restore blood flow through coronary arteries that have been narrowed due to plaque buildup. During this procedure, a surgeon inserts a catheter into the coronary artery and inflates a balloon. This balloon presses the plaque against the artery walls, thereby widening the artery to improve blood flow.

**Problem Scenario:**

Consider a diseased coronary artery with an initial diameter of 2.0 mm. To enhance blood flow by a factor of 5.0 without altering the existing pressure, to what diameter should the artery be expanded?

This involves understanding the relationship between the diameter of the artery and the rate of blood flow, often modeled by Poiseuille's Law, which states that flow rate is proportional to the fourth power of the radius.

The arterioles (small arteries) leading to an organ, constrict in order to decrease flow to the organ. To shut down an organ, blood flow is reduced naturally to 1.00% of its original value. By what factor did the radii of the arterioles constrict? Penguins do this when they stand on ice to reduce the blood flow to their feet.
A water supply maintains a constant rate of flow for water in a hose. You want to change the opening of the nozzle so that water leaving the nozzle will reach a height that is four times the current maximum height the water reaches with the nozzle vertical. To do so, should you decrease the area of the opening by a factor of 16, decrease the area by a factor of 8, (c) decrease the area by a factor of 4, (d) decrease the area by a factor of 2, or (e) give up because it cannot be done?

Fish control their buoyancy through the use of a swim bladder, a gas-filled organ inside the body. You can assume that the pressure inside the swim bladder is roughly equal to the external water pressure. A fish swimming at a particular depth adjusts the volume of its swim bladder to give it neutral buoyancy. If the fish swims upwards or downwards, the changing water pressure causes the bladder to expand or contract. Consequently, the fish adjusts the amount of gas in the bladder to restore it to the original volume and reestablish neutral buoyancy. Consider a large, 10.0 kg striped bass swimming in fresh water. When neutrally buoyant, 7% of the total volume of the fish is taken up by air in the swim bladder. Assume a constant body temperature of 15°C and neglect the mass of the air in your calculations. If the fish begins at a depth of 20 meters, what will the volume of the swim bladder be if the fish ascends to a depth of 10 m without changing the quantity of gas in the swim bladder?
