Atmospheric air pressure where standard atmospheric pressure is defined as 1013.25 mbar, 101.325 kPa, 1.01325 bar, which is about 14.7 pounds per square inch. Despite the millibar not being an SI unit, meteorologists and weather reporters worldwide have long measured air pressure in millibar as the values are convenient.
Glass typically has a tensile strength of 7 megapascals (1,000 psi). [1] However, the theoretical upper bound on its strength is orders of magnitude higher: 17 gigapascals (2,500,000 psi). This high value is due to the strong chemical Si–O bonds of silicon dioxide .
It is defined as the pressure exerted by a column of water of 1 inch in height at defined conditions. At a temperature of 4 °C (39.2 °F) pure water has its highest density (1000 kg/m 3 ). At that temperature and assuming the standard acceleration of gravity , 1 inAq is approximately 249.082 pascals (0.0361263 psi ).
Since atmospheric pressure at sea level is around 14.7 psi (101 kilopascals), this will be added to any pressure reading made in air at sea level. The converse is pound per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure ...
In aerodynamics, the normal shock tables are a series of tabulated data listing the various properties before and after the occurrence of a normal shock wave. [1] With a given upstream Mach number, the post-shock Mach number can be calculated along with the pressure, density, temperature, and stagnation pressure ratios.
To convert the Vickers hardness number to SI units the hardness number in kilograms-force per square millimeter (kgf/mm 2) has to be multiplied with the standard gravity, , to get the hardness in MPa (N/mm 2) and furthermore divided by 1000 to get the hardness in GPa.
The torr (symbol: Torr) is a unit of pressure based on an absolute scale, defined as exactly 1 / 760 of a standard atmosphere (101325 Pa). Thus one torr is exactly 101325 / 760 pascals (≈ 133.32 Pa).
