Bernoulli's law.

Classical Mechanics Level 3

Density of air is 1024.4 kg/m\(^3\). Air with a velocity of 500 km/h is moving through upper surface of the wing of a plane and air with a velocity of 400 km/h is moving through down surface of the plane's wing . The area of the wing is 100 m\(^2\) . What is the maximum possible mass (in kg) of the plane?
