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

formula_28Using the lift equation,formula_29where formula_30 is the air density, and S the wing area.

Air is made of the octahedron its minuscule components are so smooth that one can barely feel it.

This can result in more air from the previous breath remaining within the lungs when the next breath is started, resulting in an increase in the total volume of air in the lungs at any given time, a process called hyperinflation or air trapping.

When air rises, moist air cools at a lower rate than dry air.

Two main components are measured to make the diagnosis the forced expiratory volume in one second (FEV1), which is the greatest volume of air that can be breathed out in the first second of a breath, and the forced vital capacity (FVC), which is the greatest volume of air that can be breathed out in a single large breath.

Our economy is global and so are the pollutants it generates. Contaminated air from China can now be measured in other countries.

Since the majority of the cooling process results from removing sensible heat through radiant exchange with people and objects and not air, occupant thermal comfort can be achieved with warmer interior air temperatures than with air based cooling systems.

The device was even able to adjust the humidity level to a desired setting creating what would become the framework for the modern air conditioner.

Airborne volcanic ash can reflect the Sun's rays back into space and thereby contribute to cooling the planet.

An air purifier is a device which removes contaminants from the air.

Air

Using a humidifier, especially in the winter, can help by adding moisture to the dry indoor air.

A somersault can be performed either forwards, backwards, or sideways and can be executed in the air or on the ground.

Non infectious Pharyngitis may also be caused by mechanical, chemical or thermal irritation, for example cold air or acid reflux.

Air Cooler

In respect to pollution with black smoke (soot), the city zone can be divided into two zones (a) the zone of clean air, and (b) a zone of low to medium polluted air during the year, and in winter season, extremely polluted air.

This one we actually first discovered back in the air days the bad old air days, as we used to say when we were doing these kind of dives with air.

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.

Moist air has more water vapor than dry air, so more latent heat is released into the parcel of moist air as it rises.

Historians have shown evidence that carbon filtration may have been used in ancient Egyptian cultures for medical purposes and as a purifying agent.

Houses in the Air

Air pollution

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

Dry air does not have as much water vapor, therefore dry air cools at a higher rate with vertical movement than moist air.

Reducing the use of new raw materials can result in a reduction of energy usage, air pollution, water pollution and even greenhouse gas emissions.

It's acoustic vibrations in the air, little waves of energy in the air that tickle our eardrum.

This makes moist air generally less stable than dry air (see convective available potential energy).

The unit heats air at the bottom, reducing its relative humidity, and the natural tendency of hot air to rise brings this low humidity air into contact with the clothes.

He fights windmills.

The air conditioner was on.

The ratio of this air to the amount of air flowing through the engine core is the bypass ratio.

A dual hose unit draws air to cool its condenser from outside instead of from inside the room, and thus is more effective than most single hose units.

formula_4Where formula_5 is dynamic pressure.

Transport support base for the air staff.

Air pollution atmosphere

This in turn drew cooler air in from the lower vent, providing constant circulation of cooler air.

That is, for the same vertical movement, a parcel of moist air will be warmer than a parcel of dry air.

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

Many kinds of animals have vanished from the earth.

All hope of winning the game vanished.

Tear gas spreads through the air.

I was very scared.
