Power Engineering 2

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

26. Throttle body






27. Quantity ofr compressed air and delivered air by the compressor






28. One or more tube bundles - in one or more bays for an individual service or process






29. Steam expands and pressure drops as it passes through moving blades - unbalance pressure
