Question

The Bernoulli Effect helps create the lift that enables airplanes to fly. Which of the following is/are true statements about the Bernoulli Effect: circle the true statements! The air pressure over a curved airplane wing is less than underneath it The air pressure over a curved airplane wing is more than underneath it The velocity of the air flowing over the wing is higher than under it The velocity of the air flowing over the wing is lower than under it The streamlines are closer together over the wing than under it The streamlines are further apart over the wing than under it

Explanation / Answer

True statements are:

The air  pressure over a curved airplane wing is less than underneath

The velocity of the air flowing over the wing is higher than under it

The streamlines are closer together over the wing than under it

The aerodynamic lift on the wing of an airplane (airfoil) is generally explained by the argument that the faster speed of the air along the top of the wing leads to reduced air pressure there and hence produces a lift (Bernoulli's Law)
