**Elena**, Tuesday, November 27, 2012 at 1:27pmThe pressure at the depth d

p1= ρgd + p (atm) =10249.818.9 + 101325 =2.9110 ⁵ Pa,

The pressure at the height h

p=p₀exp{-μgh/RT)

Since we dont know the temperature, we use another expression.

Air pressure above sea level can be calculated as

p = 101325 (1 - 2.25577 10⁻⁵ h)⁵‧²⁶ , where

p = air pressure (Pa)

h = altitude above sea level (m)

p2=101325(1-2.2610⁻⁵4600)^5.26=5.6810⁴ Pa

ΔP=2.9110 ⁵-5.6810⁴=2.3410⁵ Pa
