Basic Hydraulics QUESTIONS AND ELABORATE
ANSWERS
What is Pascal's Law? - answer-Pressure in a liquid transmit force equally in all
directions
How is pressure measured? - answer-pounds per square inch (psi)
How is hydraulics related to Pascals Law? - answer-Because hydraulic fluid doesn't
compress, Pascal's Law states that pressure produced in a liquid transmits force
equally in all directions.
How do you find pressure? - answer-Divide pounds over square inches
How is work measured? - answer-Foot pounds (ft-lbs)
How do you find pressure? - answer-Multiply pounds moved by number of feet
moved
What is fluid power? - answer-the transmission and control of energy through the
force of pressurized liquids
How is flow measured? - answer-Velocity and flow rate
What are the two main types of flow in a hydraulic system? - answer-Laminar &
Turbulent
What happens to a hydraulic fluid when it is heated? - answer-Expands
List the three types of energy present in a hydraulic system. - answer-Potential
Heat
Kinetic
Explain the difference between laminar and turbulent flow. - answer-Laminar:
parallel; little friction
Turbulent: disturbed, increases friction
What is cavitation, and why is it destructive? - answer-Formation and collapse of
bubbles in liquid that has turbulent flow. Bubbles cause loss of lubrication and cause
wear by creating tons of force per square inch when destroyed.
What is Bernoulli's principle? - answer-the total energy of a system is the same at
all points in a system if the flow rate is constant.
Explain Bernoulli's principle in a hydraulic system. - answer-When fluid flows
through different diameters, its velocity changes. This velocity must be balanced
out by an increase or decrease in pressure.
What is the purpose of hydraulic fluid? - answer-transmit power and lubricate parts
