Which principle accurately suggests that the pressure of a fluid decreases with an increase in the velocity of the fluid?

Bernoulli's Principle describes the relation between the
pressure of a fluid and the velocity at which it is moving.

Bernoulli's principle states that as the velocity of fluid
flow increases, the pressure exerted by that fluid
decreases.

This principle has many
applications and is used extensively in our daily life. It is this principle that makes the
flight of airplanes possible. As air flows at a faster speed on the upper part of an aircraft
wing than the lower, it has a lower pressure. This makes air move upwards lifting the
aircraft.

It can also be seen when a fluid moves continuously
through a pipe. Where the pipe constricts, the speed of flow increases and there is a
corresponding decrease in the pressure.
