Density of air at 2000m
WebThe density of the air for a given level of humidity can be found by applying a correction factor to the above calculated perfect gas density. The correction factor, K h, can be found by using wet and dry bulb temperature measurements to predict relative humidity as shown in the following table. WebSep 19, 2024 · Earth's gravity pulls air as close to the surface as possible. The second reason is density. As altitude increases, the amount of gas molecules in the air decreases —the air becomes less dense than air nearer to sea level. This is what meteorologists and mountaineers mean by "thin air." Thin air exerts less pressure than air at a lower altitude.

The density of air or atmospheric density, denoted ρ, 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 atmospheric pressure, temperature and humidity. At 101.325 kPa (abs) and 20 °C (68 °F), air has a density of approximately 1.204 kg/m (0.0752 lb/cu ft), according to the International Standard Atmosphere (ISA). At 101.325 kPa (abs) and 15 °C (59 °F), air has a density of approx… WebAt an altitude of 20000 ft, an actual air density is measured to be 1.011 x 10 -3 slugs/ft 3, whereas ISA density value would be 1.267 x 10 -3 slugs/ft 3.

Then how high would the atmosphere extend? (Take g = 9.81 m/s2). Answer: Here ρ = 1.29 kg/m 3 , g = 9.81 m/s 2 , Pa = 1.01 * 10 5 Pa As, P a = h × ρ × g h = P a / ρ × g = 1.01 × 105 / 1.29 × 9.81 = 7981 m ≈ 8 km
