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

The gas oil ratio (GOR) is the ratio of the volume of gas that comes out of solution, to the volume of oil at standard conditions.

Tear gas spreads through the air.

Tear gas engulfs the air in Tunis.

Pneumoperitoneum is the presence of air or gas in the abdominal (peritoneal) cavity.

Air trapping, also called gas trapping, is an abnormal retention of air in the lungs where it is difficult to exhale completely.

Humans will have found ways of dealing with air pollution and greenhouse gas emissions.

Why? Air quality was the reason they used natural gas and got away from diesel.

It is more usual to see such techniques proposed for air capture, than for flue gas treatment.

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

Secondary recovery techniques increase the reservoir's pressure by water injection, natural gas reinjection and gas lift, which injects air, carbon dioxide or some other gas into the bottom of an active well, reducing the overall density of fluid in the wellbore.

A lot of people have now run out of cooking gas and so are cooking on wood fires the air is noticeably smoggier.

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

Fluid power is subdivided into hydraulics using a liquid such as mineral oil or water, and pneumatics using a gas such as air or other gases.

Overall pressure ratio is 28.0, with a bypass ratio of 4.66.

Overall pressure ratio is 30.4, with a bypass ratio of 5.15.

The ratio of the two is called the gyromagnetic ratio and is simply the half of the charge to mass ratio.

Another contributing factor to Japan's hay fever problem is air pollution. In addition to exhaust gas emissions, PM2.5 pollution from China is an ongoing problem in Japan.

Ayrton's interest in vortices in water and air inspired the Ayrton fan, or flapper, used in the trenches in the First World War to dispel poison gas.

Air from the atmosphere at ambient temperature, or hot water from an industrial heat source, is used to heat the liquid and turn it back into a gas.

Maternal mortality ratio

The liquid air, which takes up one thousandth of the volume of the gas, can be kept for a long time in a large vacuum flask at atmospheric pressure.

Profitability index (PI), also known as profit investment ratio (PIR) and value investment ratio (VIR), is the ratio of payoff to investment of a proposed project.

Their values vary from gas to gas.

Together Air India, Air India Cargo, Air India Express, and Air India Regional form the Air India Limited.

Rural urban population ratio

Includes figures for Batik Air, Wings Air , Malindo Air and Thai Lion Air.

In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities.

When either of the gases are mixed in excess of this ratio, or when mixed with an inert gas like nitrogen, the heat must spread throughout a greater quantity of matter and the temperature will be lower.

The new lifestyle is no longer sustainable. It s the end of the road for gas guzzling cars, glass apartments that need constant air conditioning, water thirsty washing machines, and wasteful packaging.

Select constrained aspect ratio orientation.

The air force operates from three major air bases, the 204th Batajnica Air Base and 98th Lađevci Air Base and Niš Air Base.

In aerodynamics, the aspect ratio of a wing is the ratio of its length to its breadth (chord).

Gas

The Bahrain National Gas Company operates a gas liquefaction plant that utilizes gas piped directly from Bahrain's oilfields.

The Central European Gas Hub (CEGH) is established as an important gas trading platform on the gas routes from East to West and also operates a gas exchange.
