What is the maximum weight of an aircraft with a wing of area 50m sq. flying horizontally, if the velocity of the air over the upper surface of the wing is 150m/s and that of lower surface is 140 m/s.

Answer 1

Upi meed aor density, density of air is 1.20 kg/m^3

The net lift per wing area, using the Bernoulli equation, is
(1/2)(air density)[(Vtop)^2-(Vbottom)^2]
= ......

So that is lift per m^2, and you have 50m^2
