40
Q

Bernoulli’s Principal

A

as the velocity of a fluid increases, the pressure exerted by that fluid decreases.

41
Q

Pascal’s Principal

A

Pascal’s law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.

42
Q

Archimedes Principal

A

The buoyant force is equal to the weight of the displaced water.
