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.
International Standard Atmosphere. Sea Level Conditions. Property: Metric Value: Imperial Value: Pressure: 101.3 kPa: 2116.2 lb f /ft 2: Density: 1.225 Kg/m 3: 0.002378 slug/ft 3: Temperature
Pressure, temperature, density, viscosity and speed of sound variation for the international standard atmosphere (ISA) can be calculated for a range of altitudes from sea level upward. This is done using an exact solution to the hydrostatic equation for a column of air.
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).
