the action of force upon a surface by an object, fluid, etc., in contact with it:[uncountable]air pressure. Physics the strength or amount of this force:[countable]At high pressures the wings could fall off. stress; a feeling or feelings of harassment: [countable]the pressures of daily ...
Atmospheric one is the absolute pressure of atmospheric air at the Earth's surface. This phenomenon depends on the altitude above sea level, acceleration due to gravity and weather conditions, and is usually within 93 ... 104 kPa (700 ... 780 mm Hg). Normal atmospheric pressure is taken ...
(psi, PSI, lb/in2, lb/sq in)This unit is only used in the USA. Normal atmospheric pressure is 1 atm = 14.696 psi - that means, an air colum above us of an area of 1 square inch weighs 14.696 pounds. 1 lb/in2= 6894.8 Pa =0.06895 bar 0,06804 atm = 51.715 Torr. ...
(atm)The normal air pressure is called "1 atmosphere". 1 atm = 14.6956 psi = 760 torr = 101325 Pa = 1.01325 bar. torr (torr)Torricelli barometer design: One atmosphere pressure brings a colums of mercury in a Hg barometer to a height of 760 millimeter. The pressure, which brings a co...
Altitude is calculated from air pressure and vice versa. A detailed table and plot along with descriptions of the equations are included.
Aside from air molecules, solids and liquids also exert pressure. Pressure in solids depends on the applied force or the weight of the object and the area by which the force is exerted. It is directly proportional to the applied force but inversely proportional to the area. On the other han...
- pressure units: hPa/psi, Torr/in, atm, altitude above sea level and percent of average pressure at a reference altitude - compare with reference pressure at a reference altitude - the location is automatically updated when you move - metric and imperial units - supports the iPad multitasking...
Convert Exapascals to Inch Of Air 0°C (EPa in in Air 0C). Exapascals and Inch Of Air 0°C both are the units of PRESSURE. See the charts and tables conversion here!

If you use this setting for gases other than air, you may need to scale the sonic conductance by the square root of the specific gravity. The equation for the Orifice area parameterization is less accurate for gases that are far from ideal. This block does not model supersonic flow....
