9. The blood speed in a normal segment of a horizontal artery is 0.12 m/s. An abnormal segment of the artery is
narrowed by an arteriosclerotic plaque down to one-third its normal cross-sectional area. What is the difference in blood
pressures between the normal and constricted segments of the artery? (The density of the blood is 1060 kg/m3)

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?

3. In scuba diving, a regulator is used so that the pressure of the air the diver breathes is close to that of the ambient water. A reckless swimmer decides to use a hose sticking out of the surface to breathe underwater while diving in a lake. When the air pressure in the lungs is at a pressure of around 0.155 atmospheres below the ambient pressure, lung injury may occur. Find the depth at which the swimmer would experience such a pressure differential.
