What is pressure?
It is a term that is defined from physics, however, it can also be used in different areas. It is understood as the force exerted on an object or person , is continuous, characterized by pressing and compressing. In addition to this, its movement occurs perpendicularly, that is, it acts in a straight line on the surface or body. Similarly, this term can be associated with tension, squeezing, pushing, and squeezing.
For its part, when force exerted on a person is mentioned, it refers to social pressure. This is presented and used by the social environment, it focuses on harassing an individual to meet certain demands. The objective pursued is to determine and influence decisions and attitudes as appropriate to those who exert pressure. It can be given and used by one or more individuals, a collective, a social group. In the same way, it is presented or received not only by an individual, but by several, by a group, collective or society.
However, this term is also often applied in medicine, geology, economics, sociology, anthropology and physics. In all these areas of knowledge, a similar definition is used in this regard. However, in each plays one particularly essential role and determines certain things in the area. Also, it is of great importance to mention the close relationship between temperature and pressure. Physics describe that the higher the pressure, the faster the particle movement, thus increasing the temperature.
What are its different types?
As mentioned before, this term is applied in various areas. Some of the types of pressure are explained below:
- Arterial: It is defined as arterial or blood pressure, that force exerted by the blood during its circulation throughout the system of arteries and veins. The function in which this type of pressure focuses is to serve as transport. Through this, every organ and system of the body is nourished and oxygenated .
- Atmospheric: Atmospheric pressure is understood as the force exerted by the air over the entire surface of the earth. The higher an object or human is with respect to sea level, the less atmospheric pressure there will be.
- Manometric: It is used when the force exerted is greater than that which occurs in the atmosphere. Its characteristics differ with respect to absolute pressure and atmospheric pressure, in general, it is measured with a device called a manometer.
- Absolute: This is understood and defined as the union or sum between atmospheric and gauge pressures, without these, the absolute would not exist.
- Hydrostatic: For its part, this is applied only to liquids or fluids, it represents the force and weight exerted at rest or in motion. In the first case, it is known as hydrostatic , while in the second as hydrodynamics.
Examples of pressure
- The pressure cookers, which work through the force exerted together with the increase in temperature.
- Refrigeration Elements, through pressure, exerts the movement of the liquid or gas that makes the appliance work.
- Immersion in water through diving, this puts pressure on the body that can be harmful.
- Hydraulic brakes, these are characterized by exerting pressure on the fluids that make it work.
- The pressure exerted by the air inside the tires, rims or tires.
