Air - Density, Specific Weight and Thermal Expansion ...
Online calculator, figures and tables showing density, specific weight and thermal expansion coefficients of air at temperatures ranging -100 to 1600 °C (-140 to 2900 °F) at atmospheric and higher pressure - Imperial and SI Units.
Density of air - Wikipedia
The density of air or atmospheric density, denoted ρ, [1] is the mass per unit volume of Earth's atmosphere. Air density, like air pressure, decreases with increasing altitude. It also changes with variations in atmospheric pressure, temperature and humidity.
Air Density Calculator
2024年7月30日 · Use the online air density calculator to find out the density of air at any given temperature and pressure.
Air Mass/Density | NASA Earthdata
Pure, dry air has a density of 1.293 kg m−3 at a temperature of 273 K and a pressure of 101.325 kPa. Apart from the variability of water vapor, the composition of air is essentially constant to an altitude of at least 50 km.
Air - Density vs. Pressure and Temperature
Air density at pressure ranging 1 to 10 000 bara (14.5 - 145000 psi) and constant selected temperatures. Density is the ratio of the mass to the volume of a substance: ρ = m/V [1] where. ρ = density, units typically [kg/m 3 ] or [lb/ft 3 ] m = mass, units typically [kg] or [lb]
Properties of Air - Text Version | Glenn Research Center | NASA
2023年1月21日 · Typical values of the density, pressure, and temperature of air at sea level static conditions for a standard day are: Density: 1.229 kilogram per cubic meter or .00237 slug per cubic feet. Specific Volume: .814 cubic meters per kilogram or 422 cubic feet per slug. Pressure: 101.3 kilo Newtons per square meter or 14.7 pounds per square inch.
Air Density Table and Specific Weight 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.
