PressureNoun1. The force applied to a unit area of surface; measured in pascals (SI unit) or in dynes (cgs unit); "the compressed gas exerts an increased pressure". 2. A force that compels; "the public brought pressure to bear on the government". 3. The act of pressing; the exertion of pressure; "he gave the button a press"; "he used pressure to stop the bleeding"; "at the pressing of a button". 4. The state of urgently demanding notice or attention; "the press of business matters". 5. The somatic sensation of pressure; "the sensitivity of his skin to pressure and temperature was normal".

Aerospace | 1. In a gas, the net rate of transfer of momentum in the direction of the positive normal to an imaginary plane surface of specified area located in a specified position in the gas by molecules crossing the surface in both directions, momentum transmitted in the opposite direction being counted as negative, divided by the area of the surface. In general, it is assumed that the area of the imaginary plane surface is small enough so that the pressure with respect to any part of the surface is equal (within narrow limits) to the pressure based on the whole surface. Different kinds of pressure (static, dynamic, partial, total, vapor, etc.) are distinguished by the orientation of the surface with respect to mass-flow velocity vectors or by the restriction to a specified set of molecular species crossing the imaginary surface. 2. On a boundary surface, the force applied per unit area and equal to the pressure in the gas as determined by molecules crossing an imaginary surface located at a fixed distance of molecular magnitude in front of the real surface, the positive normal being drawn from the imaginary surface toward the real surface. The term pressure when used alone can be assumed to refer to the total pressure in a gas at rest or else to refer to the static pressure in a gas flowing under steady-state conditions. 3. = atmospheric pressure. 4. As measured in a vacuum system, the quantity measured at a specified time by a so-called vacuum gage, whose sensing element is located in a cavity (gage tube) with an opening oriented in a specified direction at a specified point within the system, assuming a specified calibration factor.The sensitivity of the sensing element is, in general, not the same for all molecular species, but the gage reading is frequently reported using the calibration factor for air regardless of the composition of the gas. The opening to the gage tube is often carelessly oriented with respect to mass-flow vectors in the gas (which is seldom at rest), and errors due to variations in wall temperatures of tube and system are frequently neglected. The actual total pressure in a high-vacuum system cannot usually be measured by a single gage, but in vacuum technology the term total pressure is sometimes used to refer to the reading of a single untrapped gage which responds to condensable vapors as well as permanent gases.Symbol p.

(From Wikipedia, the free Encyclopedia)
Atmospheric pressure is the pressure caused by the weight of air above any area in the Earth's atmosphere. Standard atmospheric pressure (atm) is discussed in the next section.
Air masses are affected by the general atmospheric pressure within the mass, creating areas of high and low pressure.
As elevation increases, fewer air molecules are present. Therefore, atmospheric pressure always decreases with increasing height according to the following relationship (only a first-order approximation):
where P is the pressure in pascals and H the height in metres. This shows that the pressure at an altitude of 31 km is about 1% of that at sea level. [Source: US Department of Defense Military Standard 810E]
- ,
A column of air, 1 square inch in cross section, measured from sea level to the top of the atmosphere would weigh approximately 14.7 lb. A 1 m2 column of air would weigh about 10 tonnes.
Standard atmospheric pressure
Standard atmospheric pressure or "the standard atmosphere" (1 atm) is defined as 101,325 pascals. (see also Standard temperature and pressure)
This can also be stated as:
This "standard pressure" is a purely arbitrary representative value for pressure at sea level, and real atmospheric pressures vary from place to place and moment to moment everywhere in the world.
- 29.92 inches or 760 mm of mercury (760 torr)
- 1013.25 millibars (mb)
- 14.7 psia or 0 psig
- 0,967838490064855 at (metric atmospheric pressure).
In a low atmospheric pressure system the atmospheric pressure of the air mass is lower than that of the surrounding air. Low atmospheric pressure systems are symbolized by an L on a weather map and are associated with areas of storminess and precipitation. Wind movement is cyclonic around a low pressure system and cold fronts and warm fronts are generally connected to them.
In a high atmospheric pressure system the atmospheric pressure of the air mass is higher than that of the surrounding air. High atmospheric pressure systems are symbolized by an H on a weather map and are associated with areas of clear weather.
It is possible to demonstrate atmospheric pressure in a classroom or home environment using the crushing can experiment. See Atmospheric pressure demo

(From Wikipedia, the free Encyclopedia)
Pressure is a measure of force per unit area.
The SI unit for pressure is the pascal, equal to one newton per square metre or kg•s-2•m-1. Non-SI measures (still in use in some parts of the world) include the PSI or pound-force per square inch and the bar. In the United States air pressure is often measured in inches of mercury.
Pressure is sometimes measured not as an absolute pressure, but as the pressures above atmospheric pressure, also called gauge pressure. An example of this is the air pressure in a tire of a car, which might be said to be "thirty PSI", but is actually thirty PSI above atmospheric pressure. In technical work, this would be written as "30 PSIG" or, more commonly, "30 psig".
The standard atmosphere or atmosphere (abbreviation atm) is a curious unit of pressure, defined to six figures of precision to approximate a reality that varies constantly from place to place and moment to moment. It is approximately equal to typical air pressures at sea level and defined to be
Obsolete manometric units of pressure such as inches of water or millimeters of mercury are based on the pressure exerted by the weight of some "standard" fluid under some "standard" gravity. They are effectively attempts to define a unit for expressing the readings of a manometer.
- 1 atm = 101 325 pascal
Manometric pressure units should no longer be used for scientific or engineering purposes, due to the lack of repeatability inherent in their definitions.
The force density f (= ∂F/∂V) is equal to the gradient of the pressure: ; if it concerns the gravitational force, the force density is the specific weight.
