The dynamic lift of an aeroplane is based on

A

Torricelli's theorem

B

Bernoulli's principle

C

law of gravitation

D

continuity equation

Text Solution

Verified by Experts

The correct Answer is:
B
The lifting of an aeroplane is based on Bernoulli's principle. When airplane moves through air, pressure difference is created due to higher speed of air in the region above the wings.
