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

Most people do not suffer ill effects up to an altitude of 1800 2500 m (6000 8000 feet), and maintaining cabin pressure at this equivalent altitude significantly reduces the pressure difference and therefore the required hull strength and weight.

This was because the accuracy of the pressure altimeter (used to determine altitude) decreases with height.

To maintain a pressure in the cabin equivalent to an altitude close to sea level would, at a cruising altitude around 10,000 m (33,000 feet), create a pressure difference between inside the aircraft and outside the aircraft that would require greater hull strength and weight.

The pressure of an atmospheric gas decreases with altitude due to the diminishing mass of gas above each location.

The ICAO defines the International Standard Atmosphere, which is the model of the standard variation of pressure, temperature, density, and viscosity with altitude in the Earth's atmosphere, and is used to reduce a station pressure to sea level pressure.

However, atmospheres are not uniform in temperature, so the exact determination of the atmospheric pressure at any particular altitude is more complex.

The pressure differential was 2.5 psi (17 kPa), so at 14,700 ft (4,480 m) the cabin altitude was 8,000 ft (2,440 m).

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.

To an equatorial orbit, Skylon could deliver to a altitude or to an altitude.

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 solar altitude is 20 degrees.

formula_6 is the initial altitude (m).

Equivalent airspeed Equivalent airspeed (EAS) is defined as the speed at sea level that would produce the same incompressible dynamic pressure as the true airspeed at the altitude at which the vehicle is flying.

Acute mountain sickness can progress to high altitude pulmonary edema (HAPE) or high altitude cerebral edema (HACE), which are potentially fatal.

The city is at an altitude of .

This occurs at the altitude of geostationary orbit.

Narrator When he arches his back, he gains altitude.

Vegetation Altitude affects not only temperature, but also vegetation.

The mountainous parts of the country can be divided into several vegetation zones according to altitude, although the altitude limits of each zone may vary somewhat depending on the latitude.

YR But you feel great, but you have not the right altitude.

The maximum altitude of this storm is about above the surrounding cloudtops.

The six dimensions are usually roll, pitch, yaw, altitude, latitude, and longitude.

The altitude of each cloud represents the height of that player's tower.

Inland, the snow line in summer is at an altitude of about .

The average altitude of the park is 7.5 m above sea level.

The DRDO is also going ahead with its plans to develop a new class of UAVs, referred to by the HALE (High Altitude Long Endurance) and MALE (Medium Altitude Long Endurance) designations.

Variations in temperature are also related to the altitude of the different regions.

The lake surface was at an altitude of 1,916 m above sea level.

Sound pressure level Sound pressure is the difference, in a given medium, between average local pressure and the pressure in the sound wave.

Malaria has natural limits, determined by latitude, altitude and, in some cases, human intervention.

This altitude (r1) depends on the mass of the planet and its rotation rate.

Its highest point is Volcán Wolf, with an altitude of 1,707 m (5,600 ft).

The pressure gradient between this region and the ambient pressure will propel matter toward the low pressure area.

Atmosphere Jupiter has the largest planetary atmosphere in the Solar System, spanning over in altitude.

At that altitude, the air is so thin that aerodynamic surfaces have almost no effect.

The famed Beartooth Highway provides access from the northeast and has spectacular high altitude scenery.

At this altitude, the air density is about 1 2200000 the density on the surface.

In fact, altitude is one of the most important influences on vegetation patterns in Colombia.

The island has a total area of 4.9 km2 and a maximum altitude of 367 meters.

In response to higher altitude, the body's diffusing capacity increases in order to process more air.

Development rate depends on temperature, and to speed development, some northern and high altitude species sunbathe.

At 1530 hours, two Israeli helicopters violated Lebanese airspace at a medium altitude over Chebaa farms

Definition An atmosphere does not abruptly end at any given height, but becomes progressively thinner with altitude.
