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. An 'overrunning' clutch






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






3. Throttle body






4. The change in sped that resutls from an increase in load






5. Defined as one or more tube bundle - served by two or more fans complete with aux equipment






6. 1. single acting 2. double acting 3. two stage 4. tandem (first stage double acting - 2nd single) 5. free piston






7. Same principle as a turbine but acting in reverse






8. 1. prevent wear 2. reduce friction 3. remove heat 4. reduce corrosion 5. provide sealing






9. Simple generator - light - no battery - hotter spark at higher speeds

11. 1. control range of 0 to 100% load 2. energy efficient






12. The space wherein the liquid refrigerant absorbs heat and boils






13. Air flow is upward






14. Nickel steel - strong fully balanced rotor - expensive






15. Straight condensing






16. Rows of stationart baldes with alternating rows of moving blades






17. Cooling of air between stages - condense below atmospheric temperature removing moisture - not primary function






18. Cause high discharge pressures - more power requirements - reduces capacity






19. Reduces steam pressure and velocity in two or more steps






20. Large pressure drop - increase volume to match the increase in steam volume and pressure decreases
