Question

Bernoulli's principle gives the relationship between pressure and_________ of the fluid.

• A. density
• B. velocity
• C. volume
• D. temperature

Answer 1

The correct option is B velocity

Bernoulli's principle gives the relationship between pressure and velocity of fluids (substances that flow), i.e. liquids and gases.
According to this principle, pressure of fluid (a liquid or a gas) decreases when its velocity increases while the pressure increases when its velocity decreases.
