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






2. 1. charge drawn into cylinder is air only 2. fuel injected at high pressures 3. ignition due to high compression temperatuers






3. 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






4. 1. widely used 2. single stage 3. impulse turbine






5. Ground water monitoring device






6. Each stage seperated by partitions - nozzles set into diaphragms






7. 1. CCME 2. CEQG 3. CWQG 4. US EPA






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






9. Calcium chloride and water - -51






10. Higher power and speeds






11. Determines how much oxygen aerobic microorganisms that have been placed in the water to decompose organic matter






12. King valve






13. 'huff and puff' methods

14. DLN - reduce NOx down to 9ppm but have an increased combustion area






15. 1. can - annular 2. annular 3. single- can






16. Most widely used - least amount of steam






17. Desiccant or refrigerant 1. heatless regeneration 2. heated regeneration






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






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

32. 1. stabilize flow through air driers 2. additional moisture seperation 3. storage capacity






33. '3 ports' 1. intake and exhaust 2. compression and ignititon






34. 1. to increase steam production 2. control superheater temperatures 3. meet process demands






35. Results in pressure drop and increased velocity






36. Used on large turbines to supply lower part of the bearing with oil to prevent metal to metal contact






37. Cool compressed air before point of use

41. Throttle body






42. The condenser






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






44. A1 - A2 - A3 - B1 - B2 and B3 A = toxicity not identified under 400ppm B = toxicity identified under 400ppm 1 = not flammable 2 = low flammable limit 3 = highly flammable






45. 1. simple design 2. less piping 3. no freezing hazard






46. 1. commercial establishments 2. industrail processes 3. localized central heating of small plants






47. Primary fuel produces high thermal energy for processes - the waste heat is used to produce electrical energy
