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.
1. Used to satisfy process steam requirements






2. 1. verticle cyclinder 2. cabin heater 3. central tube wall






3. Chrome- iron alloy






4. 1. Gives perfect speed regulation 2. regulates turbine to a constant speed at all loads






5. 1. lowers power consumption 2. load changes frequently 3. pilot valve controls loading - adjustable






6. 1. increases net power 2. clean working fluid 3. cheap fuel can be used
