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.

(i) Acoustically activated fuzes use electronic sensors to react to acoustic pressure and recognize the acoustic signature.

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.

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

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.

Jeff Han shows off a cheap, scalable multi touch and pressure sensitive computer screen interface that may spell the end of point and click.

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

It's also an attention sensing system.

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.

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

DLR has tested an experimental sensor, the Bi spectral InfraRed Detection (BIRD), which is useful for monitoring fires and land surface.

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 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 movement of wind waves can be captured by wave energy devices.

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.

In that headset you have fabric sensors on your forehead and above the ear.

A sense of what was in prospect was provided by a recitation of planned missions.

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.

Remote sensing of the Earth, meteorological and environmental monitoring and natural disaster management

In this context, one can detect its roots in the experience of Germans in the Napoleonic period.

They are usually small, black or gray, with short legs, and antennae.

Section VI Fuze design and sensors of MOTAPM

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.

Actual injury is not necessary the perceived superiority of another nation is enough.

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.

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.

Air

For instance they are serving as air traffic controllers and as transport pilots in the air force.

I mean, a stag beetle it's got two points for jaws, it's got antennae. Can you be that specific in the detail?

And so we retrofit these with sensors and processors, and these robots can fly indoors without GPS.

Each site contains numerous underground sensor devices that can detect sound waves as they travel through the earth.

To determine basic categories of fuzes and adopt Best Practices on fuze mechanisms so as to increase the discriminatory capacity of MOTAPM to the greatest extent and to prevent them from being actuated by the presence, proximity or contact of a person.
