This concept is familiar from weather maps, whose isobars show the direction of geostrophic flow in the atmosphere.

A barometer measures atmospheric pressure, or the pressure exerted by the weight of the Earth's atmosphere above a particular location.

As Jupiter has no surface, the base of its atmosphere is usually considered to be the point at which atmospheric pressure is equal to , or ten times surface pressure on Earth.

Note that the boiling point of 100.0 C is at a pressure of 0.101325 MPa (1 atm), which is the average atmospheric pressure.

The airspeed is derived from the difference between the ram air pressure from the pitot tube, or stagnation pressure, and the static pressure.

For a vapor bubble to expand, the temperature must be high enough that the vapor pressure exceeds the ambient pressure (the atmospheric pressure, primarily).

For such a model atmosphere, the pressure declines exponentially with increasing altitude.

Compressed air is air kept under a pressure that is greater than atmospheric pressure.

Pressure shall preferably be exerted over a significant area (equal to that of a vehicle) rather than a single point.

The average air pressure at sea level is , with little variance throughout the year.

The direction of geostrophic flow is parallel to the isobars, with the high pressure to the right of the flow in the Northern Hemisphere, and the high pressure to the left in the Southern Hemisphere.

At atmospheric pressure, the carbon dioxide gas escapes very slowly from the supersaturated liquid.

The fire that killed the Apollo 1 crew in a launch pad test spread so rapidly because the capsule was pressurized with pure but at slightly more than atmospheric pressure, instead of the normal pressure that would be used in a mission.

And, of equal importance is, we test ARES in the Earth's atmosphere, at 100,000 feet, which is comparable to the density and pressure of the atmosphere on Mars where we'll fly.

At the elevated pressure in the bottle, more carbon dioxide can dissolve in water than at atmospheric pressure.

And we found that not only were the distributions these straight lines, but the slope of these lines, they clustered around this value of alpha equals 2.5.

Pressure Atmospheric pressure is the force per unit area that is always applied perpendicularly to a surface by the surrounding gas.

The is removed after combustion of fossil fuels, but before the flue gas is expanded to atmospheric pressure.

When surface temperature drops, eventually reaching the dew point, atmospheric water vapor condenses to form small droplets on the surface.

The liquid air, which takes up one thousandth of the volume of the gas, can be kept for a long time in a large vacuum flask at atmospheric pressure.

The Kármán line, located within the thermosphere at an altitude of 100 km, is commonly used to define the boundary between the Earth's atmosphere and outer space.

The enthalpy of sublimation, or heat of sublimation, is the heat required to sublime one mole of the substance at a given combination of temperature and pressure, usually standard temperature and pressure (STP).

Further, where an atmosphere is less dense than 0.006 Earth atmospheres, water cannot exist in liquid form as the required atmospheric pressure, 4.56 mm Hg (608 Pa) (0.18 inch Hg), does not occur.

The actual heat of combustion is 14.5 megajoules per kilogram, which requires that some of the carbon in TNT react with atmospheric oxygen, which does not occur in the initial event.

Equal opportunities

Three quarters of the atmospheric mass resides within the troposphere, and the depth of this layer varies between 17 km at the equator and 7 km at the poles.

The atmospheric mass is 93 times that of Earth's atmosphere, whereas the pressure at the planet's surface is about 92 times that at Earth's surface a pressure equivalent to that at a depth of nearly 1 kilometre under Earth's oceans.

The French mathematician Blaise Pascal reasoned that if the column of mercury was supported by air then the column ought to be shorter at higher altitude where the air pressure is lower.

The overall pressure ratio of the compression system is 24.3.

In a geostrophic flow, instead of water moving from a region of high pressure (or high sea level) to a region of low pressure (or low sea level), it moves along the lines of equal pressure (isobars).

The amount of pressure on the tissue is based on the size of the area of the contact the smaller the point of pressure, the greater effect it will have on the tissue.

In 2008 it was equal to 211 inhabitants per km².

Then the energy of the vacuum is exactly E0 .

The eutectic temperature of this mixture is .

It has a pH of approximately 7.1.

In this case, the mechanical efficiency is 100 .

Maybe on paper our company is worth less to Wall Street, but I can tell you it's worth more. We're doing fine.

With the lowest central pressure of the 2012 hurricane season, Sandy may have caused up to 20 billion in damages, making it one of the costliest superstorms in history.

After all, one plus one doesn t only equal two put together properly, it can add up to 11.

Agitators for reform will continue to push. Regime loyalists will continue to push back.

The force pushing the water towards the low pressure region is called the pressure gradient force.

Everybody knows that two and two make four.

I know you and you're nothing.

Nothing further to write, a picture is worth a thousand words.
