Air Pressure

Air pressure

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

And this in fact is exactly what air pressure is.

formula_4Where formula_5 is dynamic pressure.

It doesn't prevent me from standing up.

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

It's to be reminded that we are creatures that inhabit this ocean of air.

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

Ukraine's climates are influenced by the humid air from the Atlantic Ocean.

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.

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

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

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

It comes off the ocean here and is drawn up towards India.

We are essentially burning the airfoil as we fly it.

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

The weather front forms when the moist air over the Pacific meets the cooler continental air mass.

At that speed, the surface of the airfoil is the temperature of molten steel 3,500 degrees Fahrenheit

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

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

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

The air surrounding Greenland and Antarctica has recently become warmer and more humid.

We are a company in the field of automation, and we'd like to do very lightweight structures because that's energy efficient, and we'd like to learn more about pneumatics and air flow phenomena.

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

The plastinated specimens retain their dilated conformation by a positive pressure air flow, which allows them to be used to teach both endoscopic technique and gastrointestinal anatomy.

And, I mean, first of all we nobody had actually crossed the Atlantic in a hot air balloon before, so we had to build a hot air balloon that was capable of flying in the jet stream, and we weren't quite sure, when a balloon actually got into the jet stream, whether it would actually survive the 200, 220 miles an hour winds that you can find up there.

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.

We are free to assume the expansion happens fast enough to occur without exchange of heat (adiabatic expansion).

The wet steam that results purges the system of air and is the only remaining atmosphere in the tumbler.

A gas plume that is warmer than the surrounding air will passively emit light characteristic of its chemical constituents.

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

Let's talk about hypertension, I'll write that here hypertension

So, wherever the rain is falling, the air is drawn towards it to replace the air that's rising.
