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

Maybe a little less pressure in my chest.

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

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.

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

(c) uranium hexafluoride other than in solid form or at an internal pressure above atmospheric pressure when presented for transport.

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.

This pressure should be lower than the test pressure of the tank involved.

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.

Here is a box filled at one and a half atmospheres of atmospheric pressure, with a cloud and with very bright light.

It broke up through atmospheric pressure, it crumbled, and then the pieces fell apart and did some damage.

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

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

Where abnormal pressures or undesirable temperature conditions are present in the environment

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

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

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.

We have less pressure here than we have outside or you can view it as negative pressure.

So you would burn up due to atmospheric friction.

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

He says the disturbances are caused by subterranean waters... electric currents, atmospheric pressure, sunspots, earth tremors, et cetera.

Methane molecules account for 2.3 of the atmosphere by molar fraction below the methane cloud deck at the pressure level of 1.3 bar (130 kPa) this represents about 20 to 30 times the carbon abundance found in the Sun.

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.

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.

But the thought of applying pressure on the donors is, to say the least, nightmarish.

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.

Oxygen Supplemental oxygen is recommended in those with low oxygen levels at rest (a partial pressure of oxygen of less than 50 55 mmHg or oxygen saturations of less than 88 ).

In Ecuador, he climbed the one of the highest volcanoes, Chimborazo, so that he could record air pressure, something no one had ever done at this altitude.

This is because the partial pressure of oxygen is lower at higher altitude which, as a result means that oxygen less readily diffuses into the bloodstream.

When we think about the pressure, the output pressure, it's not the pressure at that depth of the fluid.

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).

A trace gas is a gas which makes up less than 1 by volume of the Earth's atmosphere, and it includes all gases except nitrogen (78.1 ) and oxygen (20.9 ).

As a general rule, Internet marketers try to keep the content on their squeeze pages to a minimum.

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

These reactors operate at essentially atmospheric pressure, so there's no inclination for the fission products to leave the reactor in the event of an accident.

Though less efficient, its simpler structure is less expensive than other low head turbines of the same capacity.

I am affected by the high tension powerlines. I came here after the towers were established in 2005.

That's a lot of pressure.

You get the pressure input is equal to the pressure output, so P1 is equal to P2.

It can be described as inflated self esteem, or grandiosity, decreased need for sleep, more talkative than usual, or pressure to keep talking.

The overall pressure ratio of the compression system is 24.3.
