As an example, using the ISA standard sea level conditions of P = 101325 Pa and T = 15 deg C, the air density at sea level, may be calculated as: D = (101325) / (287.05 * (15 + 273.15)) = 1.2250 kg/m 3. This example has been derived for the dry air of the standard conditions.
WebIn the metric system, which scientists use, we usually measure density in terms of kilograms per cubic meter. The air’s density depends on its temperature, its pressure and how much water vapor is in the air. We’ll talk about dry air first, which means we’ll be concerned only with temperature and pressure. WebMay 13, 2024 · Because the gravity of the Earth holds the atmosphere to the surface, as altitude increases, air density, pressure, and temperature (for lower altitudes) decrease. At the edge of space, the density is almost zero. The variation of the air from the standard can be very important since it affects flow parameters like the speed of sound.
