  2. Atmospheric pressure - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_pressure

    Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa ), which is equivalent to 1,013.25 millibars , [ 1 ] 760 mm Hg , 29.9212 inches Hg , or 14.696 psi .

    Decrease in air pressure when going from Earth sea level to 1000 m elevation [citation needed] +13 kPa +1.9 psi High air pressure for human lung, measured for trumpet player making staccato high notes [48] < +16 kPa +2.3 psi Systolic blood pressure in a healthy adult while at rest (< 120 mmHg) (gauge pressure) [44] +19.3 kPa +2.8 psi

  4. Atmosphere of Earth - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Earth

    Atmospheric pressure is the total weight of the air above unit area at the point where the pressure is measured. Thus air pressure varies with location and weather . If the entire mass of the atmosphere had a uniform density equal to sea-level density (about 1.2 kg/m 3 ) from sea level upwards, it would terminate abruptly at an altitude of 8.50 ...

    (As long as the drain hole is also blocked, as the air pressure would otherwise leak out to the atmosphere.) This is caused by the pressure in the pitot system remaining constant when the atmospheric pressure (and static pressure) are decreasing. Conversely, the airspeed indicator will show a decrease in airspeed when the aircraft descends.

    Highest air pressure: 20 January 2020, Abbeville, Somme 1049.7 hPa [184] [185] Previously: 3 March 1990, Pointe de Chémoulin, Saint-Nazaire Loire-Atlantique 1048.9 hPa. [186] Lowest air pressure: 25 February 1989, Cap de La Hague, Cherbourg 951.8 hPa. [186] though other listed figures predate Météo-France's records. [citation needed]

    This is 327 V in air at standard atmospheric pressure at a distance of 7.5 μm. The composition of the gas determines both the minimal arc voltage and the distance at which it occurs. For argon , the minimal arc voltage is 137 V at a larger 12 μm.
