Calculation of Altitude Correction - NEPSI

WebA common correction for altitude that is often used is to add a fixed temperature increment to all surface temperatures, typically 5° to 7°C to account for a fixed amount of altitude, such as 3,000m (10,000ft), regardless of convective environment or power dissipation. WebDensity Change at High Altitude. At sea level, the density of air is .075 lbs/ft 3 (1.19 kg/m 3), see Table 1. This value is created by all of the other molecules in the atmosphere weighing down on the molecules at sea level. As the elevation increases, there are fewer molecules weighing down and the density of the air decreases.
