what is the relationship between altitude and pressure?

The pressure exerted by the air in the atmosphere is greatest at Earth's surface and falls as altitude increases. The reason is that density and depth of the atmosphere are greatest at sea level and decline with increasing altitude.

Answer: As you go higher in altitude in mesosphere, the temperature decreases. Altitude and temperature in this layer in inversely proportional. The higher the altitude the lower the temperature in this layer.

Elevation masks don't change the partial pressure of incoming air; all they do is simply reduce the total amount of airflow to the lungs. ... By training in a hypoxic environment, and not changing partial pressure as altitude would, all you're doing is improving the strength and endurance of your respiratory system.

Originally Answered: What is the relationship between area and pressure alone? Pressure is defied as force over area, F/A. From the equation we see they are inversely proportional. Increasing the area decreases pressure and decreasing area increases the pressure.

Originally Answered: What is the relationship between air pressure and wind? Between an area of high pressure and low pressure, wind is the movement of air in order to (attempt to) equalise the pressure. The greater the difference in pressure, the faster the air will move.

Earth's atmosphere is about 300 miles (480 kilometers) thick, but most of it is within 10 miles (16 km) the surface. Air pressure decreases with altitude. At sea level, air pressure is about 14.7 pounds per square inch (1 kilogram per square centimeter).

High in the atmosphere, air pressure decreases. With fewer air molecules above, there is less pressure from the weight of the air above. Pressure varies from day to day at the Earth's surface - the bottom of the atmosphere. ... A low pressure system has lower pressure at its center than the areas around it.

You may already know about the relationship between temperature and pressure: When you pressurize air (or any gas), it gets hotter, and when you release the pressure on air it gets colder. ... It is this lower pressure at higher altitudes that causes the temperature to be colder on top of a mountain than at sea level.

These fronts can also cause clouds and rain, but they tend to be less violent and longer lasting. Air pressure is determined by how much the air weighs in a given space. Pressure varies with altitude, with denser air residing in lower altitudes and lighter air in higher altitudes.

We pass out when the pressure drops below 57 percent of atmospheric pressure — equivalent to that at an altitude of 15,000 feet (4,572 meters). Climbers can push higher because they gradually acclimate their bodies to the drop in oxygen, but no one survives long without an oxygen tank above 26,000 feet (7925 m).

The atmospheric pressure is about half that at sea level when you are at an altitude of 17,000 feet. A vacuum is any pressure less than the local atmospheric pressure. It is defined as the difference between the local atmospheric pressure and the point of measurement.

Atmospheric pressure decreases as the height of a surface above ground level increases. This is because, as the altitude increases: the number of air molecules decreases. the weight of the air decreases.

The greater the pressure, the greater the density. See the Ideal Gas Law. The atmospheric air become less dense with altitude, which corresponds to less pressure. If we assume that particular gas to be in a container then higher the air density, higher will be the pressure exerted as pressure depends also upon no.

P(h)=P0exp(−0.00012h). When h=0, the pressure P(h) is equal to the average atmospheric sea level pressure P0. At a certain altitude H, the pressure is twice less: P(H)=P02=P0exp(−0.00012H).

Flight levels use QNE or pressure altitude, while altitude references QNH or local pressure adjusted to sea level pressure. ... The transition between altitudes and flight levels differs by country and is generally just above the highest obstacle in that country. In the US the transition altitude/level is 18,000' / FL180.

Altitude and Density The density of air decreases with height. There are two reasons: at higher altitudes, there is less air pushing down from above, and gravity is weaker farther from Earth's center. So at higher altitudes, air molecules can spread out more, and air density decreases (Figure below).
