http://essentialpilot.co.za/2024/05/02/how-to-calculate-isa-temperature-deviation-and-why-you-should/ WebAnswer: ISA Variation = ISA-8 . Air Density varies with Height. In the Standard Atmosphere, pressure height and density height at any one point are equal. As air warms up at constant pressure, it expands. This causes the air density to decrease, since there will be fewer air molecules per unit volume, yet the pressure height will remain unchanged.

WebThe density of the air is a very important parameter in any air cooling design and especially important for high altitude air cooling. As the density of the air decreases with altitude as shown in Figure 1 the volumetric flow (m 3 /s) needed to cool the unit must increase. This means that a fan with a higher volumetric flow is needed.
