# Physics - Application of Bernouli's theorem

An airplane has an effective wing surface area of 16 m2 that is generating the lift force. In level flight the air speed over the top of the wings is 136 m/s, while the air speed beneath the wings is 129 m/s. What is the weight of the plane?(density of air 1.29 kg/m3 )

#### Solution Preview

Uplift force = Pressure difference between the top and bottom of the wings * Effective wing surface area

F (up) = [P (bottom) - ...
