aFlight level: is a derived unit of altitude used in air traffic control. One hundred feet altitude is the basic unit, therefore flight level 330 is flying at a height of 33 000 ft. 飞行水平面: 是用于空中交通管理的高度一个导出单位。 一百英尺高度是基本的单位,因此飞行水平面330飞行在高度33...
For dry air, its density at sea level at 59 °F (15 °C) and 14.7 psi (1013.25 hPa) (mean sea-level pressure) is approximately 0.0765 lb/(cu ft) (1.225 kg/(m^3)). If you change the air temperature, humidity, or altitude (and hence the pressure), the air density will change,...

Annual average atmospheric data along each route, including temperature, pressure and relative humidity (for EINOxNOx (emission index of NOxx) correction) as a function of latitude and altitude are provided by the model Atmos𝑖i. Therefore, we use the five-year mean of the DLR climate-chemist...
Air density at pressure ranging 1 to 10 000 bara (14.5 - 145000 psi) and constant selected temperatures.
where p0 is the differential pressure at the base of the vessel. In an open-based vessel, p0 can be no greater than zero and h must be modified to be the height above the water level inside the vessel rather than above the base of the vessel; the differential pressure across the air–...
