Questions and Answers

What is the main purpose of a pump in a fluid system?

  • To transfer the liquid from one location to another (correct)
  • To carry the fluid

  • Valves
  • Pumps (correct)
  • Piping

    • In what situation are pumps not needed to transfer the liquid?

  • When there is gravity flow (correct)
  • When the liquid needs to be controlled
  • When the fluid system has end-use equipment
  • When the fluid is moving upwards
