Which idea can be stated as, "The pressure exerted by a fluid decreases when

the velocity of the fluid increases"?

O

A. Flow rate equation

O

B. Bernoulli's principle

O

C. Pascal's principle

D. Archimedes' principle

B. Bernoulli's principle

Explanation:

Bernoulli's principle says that a rise (fall) in "static" pressure in a flowing fluid will always be accompanied by a decrease (increase) in the speed of the fluid, and conversely, an increase (decrease) in the speed of the fluid results in a decrease (increase) in the "static" pressure.

The Bernoulli's Principle explains the behavior of an ideal fluid passing through a pipe or enclosed passageway such a pump.
