e. Lung volumes and lung capacities refer to the volume of air in the lungs at different phases of the respiratory cycle . The average total lung capacity of an adult human male is about 6 litres of air. [ 1] Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such ...
Vital capacity (VC) is the maximum amount of air a person can expel from the lungs after a maximum inhalation. It is equal to the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume. It is approximately equal to Forced Vital Capacity (FVC). [1] [2] A person's vital capacity can be measured by a wet or regular spirometer.
The earth atmosphere's scale height is about 8.5 km, as can be confirmed from this diagram of air pressure p by altitude h: At an altitude of 0, 8.5, and 17 km, the pressure is about 1000, 370, and 140 hPa, respectively. In atmospheric, earth, and planetary sciences, a scale height, usually denoted by the capital letter H, is a distance ...
Abbreviation. AR60W. 10 meter air rifle is an International Shooting Sports Federation (ISSF) shooting event, shot at a bullseye target over a distance of 10 meters (10.94 yards) using a 4.5 mm (0.177 in) calibre air rifle with a maximum weight of 5.5 kg (12.13 lb). It is one of the ISSF -governed shooting sports included in the Summer Olympics ...
[108] [109] Blood or air with a high oxygen content is shown in red; oxygen-poor air or blood is shown in various shades of purple-blue. The lungs of birds are relatively small, but are connected to 8 or 9 air sacs that extend through much of the body, and are in turn connected to air spaces within the bones. On inhalation, air travels through ...

The 10 metre air pistol is an Olympic shooting event governed by the International Shooting Sport Federation (ISSF). It is similar to 10 metre air rifle in that it is shot with 4.5 mm (or .177) caliber air guns at a distance of 10 metres (11 yards), and that the match consists of a qualification round of 60 competition shots within 75 minutes.
At IUPAC standard temperature and pressure (0 °C and 100 kPa), dry air has a density of approximately 1.2754 kg/m 3. At 20 °C and 101.325 kPa, dry air has a density of 1.2041 kg/m 3. At 70 °F and 14.696 psi, dry air has a density of 0.074887 lb/ft 3. The following table illustrates the air density–temperature relationship at 1 atm or 101. ...
