Questions and Answers

What is the purpose of turbine technology?

  • To convert energy into heat
  • To decrease the velocity of the steam
  • To extract the maximum energy from the working fluid with maximum efficiency (correct)
  • To increase the pressure energy of steam

How does the pressure energy of steam transform in a turbine?

  • It converts into potential energy
  • It converts into heat energy
  • It converts into high velocity kinetic energy (correct)
  • It converts into electrical energy

What gives rise to a force in the turbine?

  • Increase in temperature of the steam
  • Decrease in velocity of the steam
  • Change in momentum due to the change in direction of motion of steam particles (correct)
  • Increase in pressure energy of steam
