Final answer:

As the speed of a fluid increases, pressure decreases according to Bernoulli's principle.


Step-by-step explanation:

As the speed of a fluid increases, pressure decreases.

According to Bernoulli's principle, as the speed of a fluid increases, its pressure decreases. This can be explained by considering the conservation of energy in a flowing fluid. When a fluid speeds up, its kinetic energy increases at the expense of its potential energy. As a result, the pressure decreases because there is less potential energy per unit volume of the fluid.

For example, when air flows over a wing, it speeds up and creates a region of low pressure above the wing. This difference in pressure generates lift, allowing an airplane to fly.
