Fluid Pressure

SI Unit For Pressure?

• m²

• Kelvin

• m³

• Pa

More Area , Less _______

• Pressure

• Force

• Motion

• Temperature

Bernoulli’s principle says that the faster

a fluid is moving the less pressure it

exerts.

• True

• False

What is the Calculation for Pressure?

• P = F / M

• P = F / A

• A = F / P

• M = P / A

Pneumatic chairs in hairdressing salons depend on the relationship between volume and pressure of a gas to work. When the hairdresser pushes on the lever, the volume of gas in the cylinder decreases. What happens next?

• The gas pressure increases and the chair is released back down.

• The gas pressure decreases and the chair is released back down.

• The gas pressure increases and the chair is pushed up.

• The gas pressure decreases and the chair is pushed up.

When force increases while surface area remains constant...

• pressure increases

• pressure decreases

• pressure stays the same

• pressure increases then decreases

When area increases while force remains constant...

• pressure increases

• pressure decreases

• pressure stays the same

• pressure increases then decreases

The rule that when force is applied to a confined fluid, the increase in pressure is transmitted equally throughout.

• pascal's principle

• bernoulli's principle

• archimedes' principle

• Newton's Law

A system that multiplies force by transmitting pressure from a small surface area through a confined fluid to a larger surface area.

• hydraulic system

• archimedes system

• pressure system

• bernoulli effect

Fluid pressure is directed

• in all directions.

• only upward.

• only downward.

• always sideways.
