If a scuba diver descends too quickly into the sea, the internalpressure on each eardrum remains at atmospheric pressure,while the external pressure increases due to the increased water depth. Atsufficient depths, the difference between the external and internal pres-sures can rupture an eardrum. Eardrums can rupture when the pressuredifference is as little as 35 kPa. What is the depth at which this pressuredifference could occur? The density of seawater is 1025 kg/m³.88.

The flow through a ½ in diameter pipe is 4 GPM with a pressure drop of 1 PSI. What would the pressure drop be for the same flow through a 1.5 in diameter pipe?
The tympanic membrane, or eardrum, is a structure that separates the external and middle parts of the ear (see the figure). It is sensitive to and vibrates in response to changes in air pressure and transmits these vibrations to other structures in the inner ear that lead to the sensation of hearing: Under normal conditions, the pressure on the inside and outside of the tympanic membrane are kept approximately equal. The auditory tube, also called the Eustachian tube, is responsible for this equilibration. However, rapid changes in external pressure can cause large pressure differentials on the tympanic membrane, causing it to rupture. A differential force across the eardrum membrane as little as 5.0 N can cause a rupture. (a) If the cross-sectional area of the membrane is 1.0 cm², what is the maximum tolerable pressure difference between the external and inner ear?

Tire gauges for air pressure, as well as most other gauges used in an industrial environment take into account the pressure due to the atmosphere of earth. That's why your car gauge reads 0 before you put it on your tire to check your pressure. That is called gauge pressure. The real pressure within a tire or other object contains pressurized stuff would be a combination of what the gauge reads as well at the atmospheric pressure. If a gauge on a tire reads 40.16 psi, what is the real pressure in the tire in pascals. The atmospheric pressure is 1.01x10^5 Pa.
A turbocharged aircraft engine cylinder has a total volume of 80 cu. in. and a clearance volume of 15 cu. in. The pressure in the cylinder when the piston is at TDC (Top Dead Centre) is 130 PSIA (130 pounds per square inch absolute). What is the absolute pressure in the intake manifold? What is the compression ratio?
The bends during flight. Anyone who scuba dives is advised not to fly within the next 24 h because the air mixture for PRACTICE diving can introduce nitrogen to the bloodstream. Without allowing the nitrogen to come out of solution slowly, any sudden air-pressure reduction (such as during airplane ascent) can result in the nitrogen forming bubbles in the blood, creating the bends, which can be painful and even fatal. Military special operation forces are especially at risk. What is the change in pressure on such a special-op soldier who must scuba dive at a depth of 20 m in seawater one day and parachute at an altitude of 7.6 km the next day? Assume that the density of seawater is 1029 kg/m² and the average air density within the altitude range is 0.87 kg/m³. (Walker, 2014)
Q. Blood flow. An artery of diameter 1.0 cm divides completely into capillaries, each of diameter 20 microns. There are a large number of capillaries, N, such that the net cross sectional area for these capillaries is equal to the cross sectional area of the artery. What is APc/APa, the ratio of the pressure change per unit length along one of the capillaries (AP.) to that of the pressure change per unit length along the artery (APa)? 5.0 x102 O4.0 x10-6 1.0 O1.2 x108 6.2 x1010 2.5 x105
When you hold your hands at your sides, you may have noticed that the veins sometimes bulge—the height difference between your heart and your hands produces increased pressure in the veins. The same thing happens in the arteries. Estimate the distance that your hands are below your heart. If the average arterial pressure at your heart is a typical 100 mm Hg, what is the average arterial pressure in your hands when they are held at your side?

In order to draw air into your lungs, your diaphragm and other muscles contract, increasing the lung volume. This lowers the air pressure of the lungs to below atmospheric pressure, and air flows in. When your diaphragm and other muscles relax, the volume of the lungs decreases, and air is forced out. (a) If the total volume of your lungs at rest is 5.31 L and the initial pressure is 749 mmHg, what is the new pressure if the lung volume is increased to 5.45 L? mmHg(b) If the total volume of your lungs at rest is 5.31 L and the initial pressure is 749 mmHg, at what volume will the pressure be 769 mmHg? L
