Bernoulli's theorem governs the operation of aeroplanes. The plane's wings have a certain form. When the plane is flying, the air flows across it at a high rate, although the plane's low surface wing. 

There is a differential in the flow of air above and below the wings due to Bernoulli's principle. As a result of the flow of air on the wings up surface, this phenomenon produces a decrease in pressure. If the force is greater than the plane's mass, the plane will ascend.

The nozzle of a Bunsen burner generates gas at a high velocity. As a result, the force within the burner's stem will decrease. As a result, air from the environment enters the burner.
