Question

A fully loaded boeing aircraft has a mass 3.3×10^5 kg. its total wing area is 500m^2 .It is in level flight with a speed of 960 km h^-1
a) estimate the pressure difference between the lower nd upper surfaces of the wings.
b) estimate the fractional increase in the speed of the air on the upper surface of the wing relative to the lower surface. given that density of air =1.2kg m^-3

Answer 1

Answer:

6.5 × 10³Nm⁻³

Explanation:

ΔP × A = mg

     ΔP  = 3.3 ×10⁵ ×9.8 / 500

      ΔP = 6.5 × 10³ Nm⁻³
