Which of the following describes what occurs when energy is lost in efficient transformation? -
answer✔It takes the form of heat or thermal power.
Which option identifies the type of system the engineer will design in the following scenario?
An engineer is hired to design a new dam on the James River in Virginia. He has studied the
Hoover Dam and is currently working on his design. - answer✔fluid power system
As he designs a new type of windmill, an engineer wants to be sure that there is a very strong
rotating or twisting force involved. Which word describes this force? - answer✔torque
Which of the following best describes solids, liquids, and gases? - answer✔the normal phases in
which matter exists
Which of the following is the property that describes the amount of volume that decreases
when pressure is applied to a fluid? - answer✔compressibility
Which term describes the amount of force applied to a unit of area? - answer✔pressure
What is the main difference between gases and liquids in fluid power? - answer✔Gases are
compressible.
Which term describes the ability to be productive without creating waste? - answer✔efficiency
Describe three parts of a fluid power system and the roles played by each to make the device
work. - answer✔The resevoir is a component of a fluid power system, and simply stores all the
fluids. Piping is a path upon which such fluids will travel. A pump will provide energy for the
fluids to continue travelling through the pipes.
Which of the following do pumps provide to a fluid power system? - answer✔energy
Ethan is an engineer who is trying to create a totally quiet fluid power system. Which part of
the fluid power system will he need to redesign? - answer✔compressor
Hydraulic systems are susceptible to contaminants. Which of the following must be used to
ensure that the fluid remains clean? - answer✔filters
Which of the following explains the role of instruments such as gauges, sensors, and pressure
switches in a fluid power system? - answer✔They are used to control, maintain, and monitor
the fluid power system.
Which option identifies the type of system that will be designed in the following scenario? Josh
is an engineer who is hired to redesign a chair for the elderly; it is mobile but can also rise up
and down to reach different heights. - answer✔a pneumatic power system
Which of the following is a mechanical device that presses gases into a small container? -
answer✔compressor
Which type of engineer works with chemicals to develop safety precautions, repairs chemical
manufacturing equipment, and creates processes to work with liquids and gases? -
answer✔chemical engineer
1.An engineer designs a system in a car: As the car engine starts, the fuel turns to heat, and the
heat is absorbed into the car to provide an additional source of energy.
2.An engineer designs a system on the exterior of an aircraft that senses the force of the
atmosphere at the aircraft's current altitude.
3.An engineer designs a screw that can introduce or prevent motion in his newest design: A
helicopter that can become airborne in less than 10 seconds. - answer✔2 static pressure
3 actuator
1 transformation
1.An engineer has designed a fluid system, but the actuator is moving too fast, forcing the
engineer to make adjustments
2.An engineer is adjusting his design for a pool's filtration system.
3.An engineer is redesigning a fluid pump at a gas station so that there is no leakage while the
pump is at rest. - answer✔2 moving fluid system
3 stationary fluid system
1 flow rate
1.Ahmed is looking for a new way to extract fuel sources like oil and natural gas while
decreasing the risk of damage to the environment.
2.After watching news footage of oil spills in the Gulf of Mexico, Bill decides to learn more
about jobs designing products that can help clean up the environment after petroleum spills.
3.Deanna is partnering with a team to increase efficiency in current fluid power applications.
She is hoping to decrease the amount of energy lost with most hydraulic power systems by
redesigning the existing hydraulic systems in construction vehicles. - answer✔2 researching a
geologic sciences career
1 working as a petroleum engineer
3 working with the Center for Compact and Efficient Fluid Power (CCEFP)
1.a system in which fluid does not flow
2.the volume of fluid that moves through a system in a given time
3.a fluid system component that introduces or prevents motion
4.the force exerted by a fluid that is distributed equally in all directions - answer✔1 stationary
fluid system
3 actuator
4 static pressure
2 flow rate
1.An engineer's design is acclaimed by the CCEFP. It will reduce the amount of waste that a jet
plane produces by 24 percent, thereby reducing overall fuel costs.
2.An explosion has occurred on an offshore oil rig. Engineers work around the clock to be sure
there was no major damage done to the pipeline.
3.A pressure system is devised to bring water to a remote village in Africa that has very little
access to electricity. - answer✔3 fluid power system
1 efficiency
2 high pressure
Transformation is the change of one energy form to another. - answer✔true
Scientist Blaise Pascal researched the relationship between fluids, energy systems, and
pressure. - answer✔true
