Orders of magnitude (pressure)
From Wikipedia, the free encyclopedia
| Pressure | Item |
|---|---|
| 1 fPa | Interstellar space pressure (approximate) = about 1 gas atom per cubic meter |
| 1 nPa | Atmospheric pressure on the Moon (approximate) |
| 1 µPa | Pressure inside a vacuum tube. (approximate, varies) |
| 20 µPa | Threshold of human hearing. The smallest RMS pressure fluctuation that the human ear can hear in a noiseless environment, at frequencies between 1 and 5 kHz. |
| 100 µPa | Near earth outer space pressure. (approximate) |
| 0.5 Pa | Atmospheric pressure on Pluto (1988 figure; very roughly). |
| 1 Pa | Pressure exerted by a house fly standing on a postage stamp in vacuum (approximate). |
| 10 Pa | Pressure increase per millimeter of a water column.1 |
| 10 Pa | Pressure inside an incandescent light bulb (approximate). |
| 100 Pa | Threshold of pain. Sounds above this amplitude are unbearable and can cause ear pain.
Prolonged exposure may lead to hearing loss. |
| 1 kPa | Atmospheric pressure on Mars; 1 % of atmospheric sea-level pressure on Earth. |
| 10 kPa | Pressure increase per meter of a water column1, or the drop in air pressure when going from earth sea level to 1000 m elevation. |
| 101.325 kPa | Standard atmospheric pressure for earth sea level |
| 180 to 250 kPa | Pressure in an automobile tire. |
| 0.8 to 2 MPa | Pressure used in boilers of steam locomotives. |
| 9 MPa | Atmospheric pressure on Venus |
| 10 MPa | Pressure washers force out water at this pressure. |
| 12 MPa | Pressure exerted by a 60kg woman wearing stilettos. |
| 20 MPa | Pressure of a typical aluminium scuba tank. |
| 100 MPa | Pressure at bottom of Mariana Trench, about 10 km below ocean surface. |
| 400 MPa | Chamber pressure of .50 BMG weapon discharge |
| 10 GPa | Pressure at which diamond and tetraoxygen forms. |
| 100 GPa | Theoretical tensile strength of a carbon nanotube (CNT). |
| 380 GPa | Pressure inside the core of the Earth |
| 530 TPa | Pressure inside an Ivy Mike-like nuclear bomb |
| 6.4 PPa | Pressure inside a W80 warhead detonation |
| 35 PPa | Pressure inside the core of the Sun |
