Air Pressure

Air pressure

The differences in temperature make differences in air pressure, and the differences in air pressure make air move.

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

Low pressure air rises from the equator and meets high pressure air from the poles.

So air always wants to go from high pressure to low pressure and so air is going to flow into our lungs.

Breathing is all about moving air from a higher pressure to a lower pressure environment.

And then it's inflated with this low pressure air.

And this in fact is exactly what air pressure is.

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

I don't just feel the weight of air coming from above, I actually feel that pressure pushing from all directions which is why air pressure isn't a burden.

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

It is compliant. You can actually change the force, simply just changing the air pressure.

If there's a region of low pressure in the atmosphere, air is pushed toward it,

Hot humid air rose up to create several thunderstorms around an area of low pressure.

In air, sound pressure can be measured using a microphone, and in water with a hydrophone.

We are calling all who are in charge to release the sanctions on Syrian Air, Syrian Air have the right to buy spare parts and aircrafts..

The Air Operations Assistant acts as Officer in Charge in the absence of the Chief Aviation Officer.

As the vapor pressure increases, the concentration of vapor of the flammable liquid in the air increases.

Changing the air pressure going into the lungs is one of the main ways to alter breathing.

It's the internal air pressure of the helium, or your own exhales that you put into the balloon.

Significance By observing the mercury in the column while releasing the air pressure with a control valve, one can read the values of the blood pressure in mm Hg.

A total of 320 compressed air workers were involved in 9018 pressure exposures in the four tunnel boring machines.

The barometers plummeted dramatically according to calculations the air pressure must have decreased to 950 millibars, a rare low for Britain.

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.

So when water molecules (water vapor) are added to a given volume of air, the dry air molecules must decrease by the same number, to keep the pressure or temperature from increasing.

I need air volume as much as possible in my lungs to be able to equalize against the pressure as I descend.

The greatest reduction in air flow occurs when breathing out, as the pressure in the chest is compressing the airways at this time.

Along the way, he took measurements about the shape of the land, its temperature, the air pressure, and the strength of magnetic fields.

The most visible natural occurrence of this is lightning, caused when charge becomes separated in the clouds by rising columns of air, and raises the electric field in the air to greater than it can withstand.

The most familiar charge is electric charge.

In reality, due to currents, air pressure variations, temperature and salinity variations, etc., this does not occur, not even as a long term average.

At times of high demand for electricity, the liquid air is pumped at high pressure into a heat exchanger, which acts as a boiler.

And if that vapor pressure is high enough, you can almost view them as linemen blocking the way for more molecules to kind of run behind them as they block all of the other ambient air pressure above them.

As the wind blows, pressure and friction perturb the equilibrium of the water surface and transfer energy from the air to the water, forming waves.
