At 101.325 kPa (abs) and 15 °C (59 °F), air has a density of approximately 1.225 kg/m 3 (0.0765 lb/cu ft), which is about 1 ⁄ 800 that of water, according to the International Standard Atmosphere (ISA).
Standard Atmosphere Modeling. For purposes of pressure altimeter calibrations, aircraft and rocket performance and their design, and so forth, knowledge of the vertical distribution of such quantities as pressure, temperature, density, and speed of sound is required.
Description. The ISA mathematical model divides the atmosphere into layers with an assumed linear distribution of absolute temperature T against geopotential altitude h. [2] . The other two values (pressure P and density ρ) are computed by simultaneously solving the equations resulting from:
Air Density and Specific Weight Table, Equations and Calculator: The density of air, ρ (Greek: rho) (air density), is the mass per unit volume of Earth's atmosphere. Air density, like air pressure, decreases with increasing altitude. It also changes with variation in temperature or humidity.
Air is a mixture of gases at standard conditions. However, at low temperature and high pressures the gas mixture becomes a liquid. The phase diagram for air shows the phase behavior with changes in temperature and pressure.
