Find the pressure difference (in kPa) on an airplane wing if air flows over the upper surface with a speed of 125 m/s, and along the bottom surface with a speed of 109 m/s. [Express answer in TWO decimal places]

P = 2414.9 Pa

Explanation:

given

density of air, p = 1.29 kg/m³

speed of air over the upper surface, v₁ = 125 m/s

speed of air over the lower surface, v₂ = 109 m/s

the pressure difference on an airplane wing, P = 0.5 * p * (v₁² - v₂²)

P = 0.5 * 1.29 * (125² - 109²)

P = 0.645 (3744)

P = 2414.9 Pa

the pressure difference on an airplane wing is 2414.9 Pa
