This air has its temperature and pressure corrected before being fed into the cabin.
They adjust the temperature and pressure of the mix to mimic conditions at various heights above sea level.
Synthetic diamonds, made by compressing diamond shards under high temperature and pressure, are less brittle and wear more evenly than natural diamonds.
Hurtling towards the stratosphere the balloon was fitted with weather instruments designed to measure, among other things, temperature, pressure and wind speed.
Filling a typical fuel tank of 75 litres about 20 American gallons with hydrogen at room temperature and pressure will take a hydrogen-powered car only about a kilometre or so.
ECONOMIST: Chicken feathers could provide a high-capacity store
Gravity bombs are designed to be dropped from planes and must be able to withstand vibrations and changes in air temperature and pressure during the course of a flight.
Feathers scorch if you heat them too much, so the researchers have to keep the temperature and pressure within the narrow range that make feathers malleable without burning them.
As protection against the extremes of temperature and pressure which were to come, he had taken just one precaution - he had stuffed bits of crumpled white tissue paper into his ears.
At a high temperature and pressure, gasification converts coal, or other carbon fuels, into synthesis gas that is either burned in a turbine to produce electricity, as in Summit's case, or turned into other products, like diesel oil, fertilizer and pipeline-quality natural gas.
Since most objects in the asteroid belt are primitive, dating back to the beginnings of the solar system, the information they hold their chemistry, and the temperature and pressure under which they were created can be used to understand what conditions were like when the planets formed.
Information pours in from scoresof sensors that constantly read temperature, barometric pressure and load.
BeagleBone Weather Cape provides data including temperature, barometric pressure, humidity and ambient light.
ENGADGET: BeagleBone gets plenty of expansion options with new 'cape' add-ons
For now, aeroplanes and rotors are not slathered routinely with temperature-and pressure-sensitive paints because their sensitivity needs to be improved.
Then in the early 20th Century, German chemist Fritz Haber invented a high temperature-high pressure technique to convert atmospheric nitrogen into ammonia.
Right now the focus is on humidity, temperature and barometric pressure, though other environmental variables would be relatively trivial to tack on.
At the bottom of the Knotty Head hole, the 450-degree-Fahrenheit temperature and the pressure (2, 000 times atmospheric) would crush or melt most drilling tools.
An ideal one would keep the same rate regardless of variation in power supply, temperature, air pressure, magnetic fields, or any other disturbing influences.

In their latest experiment, Dr Sullivan and his colleagues painted the blades of a rotor with both temperature-and pressure-sensing paints, shone laser light on to them, and mapped out the temperatures and pressures as the blades whirred around as fast as 14, 000 rotations per minute.
"When you take off from Daytona until May, there's so many things you need to orientate yourself with something as simple as just being able to see the water temperature and water pressure gauges in your peripheral without having to pay attention to them, understanding how the cars move when other cars come around you, " Waltrip said.
It's an airtight pod that changes air pressure, temperature and density.
It has patented a number of the items needed to complete high pressure, high temperature wells.
FORBES: Shortsellers Party Hearty After Their Cheerleader Says McMoRan Is Worth Zero
In 1931 American chemical engineer Samuel Kistler invented the lightest known solid--an aerogel--by drying a form of silicon dioxide (a raw material for glass) under intense pressure and high temperature.
Analysis in the 70s and 80s variously suggested that high pressure, high temperature and low humidity were associated with positive emotions - basically, nice weather seemed to put people in a good mood.
Each sensor, which is shaped like a hexagon and is about twice as thick as a hockey puck, is capable of monitoring the temperature, humidity and barometric pressure of virtually any object you can think of.
With the engine running, he can see on-screen how much fuel should be injected given X throttle pressure or Y coolant temperature.
In this highly competitive and sometimes harsh environment, marine species have had to develop strategies for survival, such as resistance to the toxicity, extreme temperature, hyper-salinity and pressure that characterize the deep seabed.
"Through embedded sensors, the probes can measure a tornado's wind speed and direction, barometric pressure, humidity, and temperature, " the magazine wrote.
It meets the highest standards of resistance to dust, sand, shock, vibrations, low pressure, high and low temperature, rain and long-term moisture.
As you may remember from physics class, changing the pressure of a liquid changes its temperature.
