The function of the pump in a Hydraulic system is to create pressure

• True

• False

What components in a hydraulic system does not allow system pressure to exceed its maximum pressure setting?

• Accumulator

• Flow control valve

• Pump

• Pressure control valve

Fluid pressure is:

• Force

• Force over area

• Force multiply by area

• Area over force

Pascal's law states that a liquid

• is relatively incompressible

• can take the shape of the container

• is made up of small particles

• transmit pressure equally throughout itself

The primary function of a hydraulic fluid is

• transmit power

• provide thermal energy

• dissipate potential energy

• create kinetic energy

a vacuum pressure of 4" Hg at sea level is the same as

• 1.5" psi

• 24" Hg

• 6"Hg

• 1.964 psi

absolute pressure is exactly the same as

• Gauge pressure

• atmospheric pressure

• atmospheric plus gauge pressure

• none of the above

the proper way to handle a spill is to:

• clean all the spills immediately

• use approved methods

• prevent skin contact or breathing fumes

• all the above

force propagates through solids in one direction but with the different magnitude

• True

• False

how an air bubble gets in the pump

• coming out of the oil

• localized boiling

• mechanical entrapment

• all the above
