Applications of Bernoulli's theorem can be seen in

Options

A. dynamic lift of aeroplane
B. hydraullic press
C. helicopter
D. none of the above

Answer

A

Explanation

Ac cording to Bernoulli's theorem, when aeroplane moves, the air streams are created on upper and lower face of the wings of aeroplane. Then velocity of air streams on the upper face is more than on lower face. Ac cording to Bernoulli's theorem, the pressure is more on lower face than on upper face of the wins of aeroplane. This provides a lift on the aeroplane for its flight.
