Density of air in atmosphere
WebAir - Density, Specific Weight and Thermal Expansion Coefficient vs. Temperature and Pressure - 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. WebThe density of air at an altitude of 16 km (50,000 feet) is only about 13% of the density of air at the surface. The red curve in the top panel of Figure 6.01shows a typical vertical profile of density from the ground to 60 km. The density of air near the top of the stratosphere is nearly zero.
