air pressure 有可能是仪表风的压力，air不一定是空气，也可以是仪表风啊
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. ...
Atmospheric Pressure the hydrostatic pressure exerted by the atmosphere on all objects in it. Atmospheric pressure is a fundamental characteristic of the atmosphere’s condition; at each point in the atmosphere it is determined by the weight of the overlying air. Atmospheric pressure decreases with he...
A unit of pressure: the pressure that will support a column of mercury 760 mm high at sea level and 0 degrees centigrade Air A solo with or without accompaniment. Atmosphere The mass of air surrounding the Earth; There was great heat as the comet entered the atmosphere It was exposed to ...
When the number of gaseous molecules tends to occupy the specific volume of the container such that each molecule applies some magnitude of pressure at the walls of the container, then the pressure applied by each molecule is called partial pressure....
A compressed air volume flow of 10 acfm (actual cfm) at 100 psig must be multiplied with Compression Ratio approximately 8 to estimate the volume of free air at atmospheric pressure. qF = 8 (10 acfm) = 80 scfm (standard cfm) Compression Ratio - Pressure (bar) Example - Converting Fre...
