A fully loaded boeing aircraft has a mass of `3.3xx10^(5)kg` . Its total wing area is `500m^(2)` .It is in level flight with a speed of `96.km//h`.
(a) Estimate the pressure difference between the lower and 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. (The density of air is `rho=1.2kgm^(-3))(g=9.8ms^(-2))`

Explanation

`DeltaP=8000Nm^(-2),(b)(v_(2)-v_(1))/(ltvgt)=0.094`
