Concept explainers

Fluid Pressure

The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.

Gauge Pressure

Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

### Blood Flow Dynamics through Constricted Arteries

Plaque builds up on the walls of an artery decreasing its diameter from **1.16 cm** to **0.66 cm**. If the flow speed is **16.0 cm/s** before reaching the region of plaque buildup, determine the following:

#### (a) Speed at which blood is traveling through the plaque-constricted region
\[ \_\_\_\_\_\_\_\_ \, \text{cm/s} \]

#### (b) Pressure change within the plaque-constricted region
(Assume the density of blood is **1050 kg/m³**. Be sure to include the appropriate sign with your answer.)
\[ \_\_\_\_\_\_\_\_ \, \text{Pa} \]

---

To solve these problems, you would typically use the principles of fluid dynamics such as the continuity equation and Bernoulli’s principle.

As blood goes from the left ventricle through the arteries and veins of the human body, both its speed and pressure change. The arteries and arterioles can either constrict, reducing the area, or dilate, increasing the area, in response to certain conditions. Both of these changes can affect blood flow and blood pressure. An artery can also develop a permanent narrow area (stenosis) or a permanent wide area (aneurysm). Both of these changes can have significant health consequences. A patient has developed an aneurysm in the aorta, a short section where the diameter is twice the normal diameter. In the aneurysm, the speed of the blood is ______ than in the section before the aneurysm, and the pressure is _________ than in the section before the aneurysm.A. Greater, greater B. Greater, lessC. Less, greater D. Less, less
A fish tank has dimensions 42 cm wide by 1.0 m long by 0.80 m high.If the filter should process all the water in the tank once every 3.0 h, what should the flow speed be in the 3.0-cm- diameter input tube for the filter?Express your answer to two significant figures and include the appropriate units.
At 20°C, the viscosity of water is 1.0x10-3 Pa-s and the viscosity of molasses is 51 Pa-s. Consider two tubes of the same length L, with fixed pressure difference Ap across each pipe. If water flows through Pipe 1 and molasses flows through Pipe 2, and both have the same flow rate Q, what is the ratio of the radius of Pipe 2 to Pipe 1?
When a person inhales, air moves down the bronchus (windpipe) at 13.8 cm/s. The average flow speed of the air doubles through a constriction in the bronchus. Assuming incompressible flow, determine the pressure drop in the constriction. Neglect the change of pressure due to change in height ?y in the wind pipe. If the pressure goes down then the pressure drop is negative. Use 1.20 kg/m33 for the density of air.
