WebAug 8, 2024 · ρ is the air density, which is a function of air temperature: ρ = p s R ⋅ T. For indicated airspeed, the density at sea level ρ S L at 15 degC is taken: V i = 2 ⋅ ( p t − p s) ρ S L. However, the actual dynamic pressure measured by the pitot tube is caused by actual density. When temperature decreases, density increases. There are two equations for computing pressure as a function of height. The first equation is applicable to the standard model of the troposphere in which the temperature is assumed to vary with altitude at a lapse rate of $${\displaystyle L_{b}}$$: $${\displaystyle P_{b}}$$ = reference … See more The barometric formula is a formula used to model how the pressure (or density) of the air changes with altitude. See more • Hypsometric equation • NRLMSISE-00 • Vertical pressure variation See more The expressions for calculating density are nearly identical to calculating pressure. The only difference is the exponent in Equation 1. There are two … See more WebAnswer: Solution: The atmospheric pressure varies with altitude as density of air decreases as we rise up and air becomes rarer. For example: Pressure at sea level is taken as 76 cm of Mercury Column, which is one atmosphere. For every 105m rise in height, pressure decreases by 1 cm of mercury column.
