Bernoulli's law.

Density of air is 1024.4 kg/m 3 ^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 ^2 . What is the maximum possible mass (in kg) of the plane?

Submit the nearest integer value to your answer.


The answer is 3556947.

Use the formula,
P + 1/2 p v^2 + p g h = constant

I'm afraid you wrote wrong th density of the air...

The value that I came up with, it's simply absurd for airplane wing!
