Questions and Answers

Based on the text, which methods are explicitly mentioned as principal methods for driving compressors?

  • Electric motors, gas turbines, and internal combustion engines (correct)
  • Water turbines, solar panels, and wind turbines
  • Geothermal energy, nuclear reactors, and fuel cells
  • Hydraulic motors, steam engines, and pneumatic systems

In which scenario would gas turbines typically NOT serve as a drive source for compressors?

  • To drive large centrifugal compressors re-pressurizing natural gas pipelines
  • To drive compressors in underwater applications
  • To drive compressors in space stations
  • To drive small portable compressors in residential areas (correct)

When are internal combustion engines commonly NOT employed as a drive source for compressors?

  • During extreme weather conditions and natural disasters
  • During power failures and to drive emergency compressors
  • In underwater applications and marine environments
  • During normal operations and for continuous service compressors (correct)
