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






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






3. Nickel steel - strong fully balanced rotor - expensive






4. U- tubes - surface areas less than 18 cubic meters - has small heat transfer surface






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






6. Use antifriction bearings






7. Use teflon or carbon to lubricate system






8. HCFC group - miscible in oil - boiling point of -40.8 but can be used down to -87






9. Made of polyethylene - skimming from the surface






10. 1. individual pump system 2. distributor system 3. common rail system






11. 1. contact - 'jet' 2. surface






12. The condenser






13. Has the highest level of thermal efficiency - low capital costs - fast start up - quick to build - low maint cost






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






15. Cannot go below -18






16. Sagging and hogging - 20-40rpm






17. 1. titling pad Kingsbury (journal bearing) 2. Michel thrust bearing






18. Refers to the production of power during overload demands






19. Equal and opposite reation

20. 1. use clean burning fuels 2. less fuel being used - saving energy reserves 3. electrical production onsite lowers construction demands for new sites and reduces transmission line power losses






21. Controlled pressure from intermediate stages of turbine






22. HFC group - zero ozone depletion - nonflammable and nonexplosive - boiling point of -26.2 - miscibility problem with minerial oil - use sythetics ester based






23. 1. backpressure 2. condensate levels 3. contanimation 4. vacuum pay- off relays (10 to 40kPa) 5. vacuum trip relays (50kPa)






24. Polymers (polyelectrolytes)






25. Servomotors






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






27. A concentrated solution at its critical point






28. Non - condensing turbine exhaust steam at...






29. Produce and maintain a vacuum at the turbine exhaust allowing steam to expand to a lower pressure and do more work






30. Calcium chloride and water - -51






31. Radiator type






32. Ground water monitoring device






33. 1. planning 2. implementation 3. review






34. No dissolved oxygen but does contain nitrates






35. 1. need cooling water 2. low hx efficiencies 3. complex in size - increase in costs






36. 0.577 times the inlet pressure






37. 1. compression ration across compressor 2. turbine inlet temperature






38. Wrist pins that connect pistons to rod - retained bu circlips






39. 1. kettle 2. thermosyphon horizontal 3. thermosyphon vertical






40. Have advantage of high efficiencies - 10% greater than centrifugal compressors






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






42. Contains 0.5kg of moisture for every 28 cubic meter of air






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






44. Working fluid is compress then preheated in regenerator






45. Monel metal - high tensile strength - nickel copper alloy






46. KW at 15C standard at sealevel with 60% RH






47. 1. deman reservoir 2. avoid overloading compressor 3. dampens deew point and temperature spikes rom air dryer






48. 1. plate 2. channel






49. Admirally brass or Munte metal - 25-40mm thick






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