air pressure n (degree of atmospheric force) (空气压力的衡量单位)气压The current temperature is -1, and the air pressure is 1016 millibars. air pump n (device: inflates tyres)打气筒;气泵To inflate our car tires, we use the air pump at the gas station instead of the bicycle pump at ...
kilobars to foot of mercuryDefinition: KilobarThe SI prefix "kilo" represents a factor of 103, or in exponential notation, 1E3.So 1 kilobar = 103 bars.The definition of a bar is as follows:The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (ba...
1.the pressure exerted by the earth's atmosphere at any given point. 2.a value of standard or normal atmospheric pressure, equivalent to the pressure exerted by a column of mercury 29.92 in. (760 mm) high, or 1013 millibars (101.3 kilopascals). Also calledbarometric pressure. ...
P = atmospheric pressure, in millibars; V = volume between the marks of the volumeter tube, in cubic centimeters; t = time required for the bubble to travel between the marks, in seconds; X = flow rate, in cubic centimetres per second. ...
Normal air pressure = 1.01325 bar = 1013.25 mbar. millibar (mb or mbar) 1000 millibars are 1 bar. Meteorologists like this. 1 millibar = 0.001 bar = 0.750 Torr. 1 mbar = 100 Pa = 1 hectopascal. microbar (µb or µbar) 1 microbar is 10−6 bar = 1 dyne/cm². 1µbar...
where ρ0 is the mass density at standard temperature and pressure (0°C and 760 mm Hg), P is the pressure in millibars, and T is the temperature in kelvins. The number of molecules per unit volume of any gas at fixed temperature and pressure is independent of the gas type (Avogadro...
This decreases the quantity of air in that area, and therefore decreases the atmospheric pressure. 这使得该地区的空气质量减小,因此减少了大气压强。 —— 给力词典精选 5. For instance, atmospheric pressure on Mars is only a fraction of what it is here on Earth - averaging 7.5 millibars on Mars...
getPressure(): returns the barometric pressure (in millibars) measured at this monitoring station at the time of measurement. getPrimaryPollutant(): returns the name of the primary pollutant at this monitoring station at the time of measurement (e.g. 'pm25'). Changelog Please see CHANGELOG for...
The SI prefix "tera" represents a factor of 1012, or in exponential notation, 1E12.So 1 terabar = 1012 bars.The definition of a bar is as follows:The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square ...
Millibars, Inches of Mercury, and Pascals Barometric pressure can be reported in any one of the below units of measure: Inches of Mercury (inHg) - Used mainly in the United States. Millibars (mb) - Used by meteorologists. Pascals (Pa) - The SI unit of pressure, used worldwide. Atmosph...
