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. Higher power and speeds






2. Cannot go below -18






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






4. Fall under provincal boiler pressure regualtions - wcb and local fire marshall regulation and insurance company - need log book - safety device testing records






5. Type of hydrometer indicating % of salt in solution






6. 1. Nozzle - impulse turbine only 2. throttle - reaction turbine only 3. bypass or overload - used on both turbines






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






8. Ground water monitoring device






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






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






11. Too small to settle out - add floc






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






13. Moisture removed by centrifugal force






14. 1. Single flow 2. double flow 3. automatic extraction 4. backpressure






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






16. 1. spray 2. fog 3. special evaporator pads






17. The difference between the no- load and full- load speed - expressed as a %






18. Requires annual review of SOPs






19. Does not contain dissolved oxygen






20. Either fixed production or varying






21. An 'overrunning' clutch






22. Reversal of flow within a compressor - rush in from discharge side sending a shock wave inside compressor






23. Increase pressure affecting performance of condenser but do not incresase temperature






24. Cast with special nickel based alloys - Inconel - Udimet - Waspalloy - Hastelloy






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






26. Chrome- iron alloy






27. Refers to the production of power during overload demands






28. 1. Carbon ring 2. labyrinth seal 3. water seal






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






30. 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






31. Waste heat only






32. Meters liquid from liquid line into evaporator at a rate equal at which vaporization of liquid is occuring






33. 1. activated sludge 2. rotating biological contactors 3. trickling filters






34. 0.577 times the inlet pressure






35. Seperately forged discs or wheels and shrunk onto shaft






36. 1. sliding vane 2. rotary lobe 3. rotary screw ( convex male lobes - pulse free)






37. Entire collection of all component

38. 1. list of all equipment 2. PM checklist 3. fequency 4. repairs and costs 5. record keeping 6. cost management






39. 1. Aero- derivate 2. Heavy duty






40. Control a steady backpressure - sensing element in exhuast line






41. Has steam directed through baffles making 4 passes






42. 1. vent to atmosphere 20% 2. condensing 30% 3. exhaust steam used for work 80%






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






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






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






46. Removal of exhaust gases by blow air through






47. Cool compressed air before point of use






48. A verticle well is used to increase the NPSH - gives better performance and less cavitation






49. 75 -000 to 100 -00 hours of operation






50. 1. start and stop control (reciprocating compressors) 2. variable speed (dymanic and rotary compressors) 3. constant speed (positive displacement)
