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






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






3. Center- to- center distance between baffles






4. The utilization of one form of input energy to generate two or more forms of output energy






5. 1. Split 2. double






6. 5mm in diameter






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






8. Means to come together and form one mass - removes oil and water from air






9. Grit chambers and screens for waster water system






10. Reduction of NOx through ammonia injection priot to catalyst - lowering NOx to 10ppm






11. Eliminates thrust - steam admitted midway along casing






12. Has steam directed through baffles making 4 passes






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






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






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






16. Independant of the governor - inductive sensor (magnetic speed pickups)






17. 1. brass 2. copper 3. cupronickel






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






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






20. The crankshaft and valve train






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






22. Atmospheric or hyperbolic






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






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






25. 1. reduce total energy bill 2. compact - les maintenance 3. short start up time 4. wide range of configurations






26. Compression ignititon engines






27. Use teflon or carbon to lubricate system






28. Removal of exhaust gases by blow air through






29. Pressure drops across the moving blades






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






31. Up to 60-90%






32. 'booster' compressor






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






34. 1. plate 2. channel






35. 1. evaporator coil






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






37. 1. electricial purity 2. silver nitrate - milky white






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






39. Velocity increases as passes through nozzles






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






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






42. Good thermal properties - boiling point of -33.3 - pure anhydrous ammonia is noncorrosive - cheap - not miscible in oil - toxic






43. Small pressure drop






44. CFC group - safe nontoxic - but long atmospheric life span of 100 years - boiling point of -29.8






45. Dry surface coolers - no contact convection hx - aka finned tube exchangers






46. 1. operates on a temperature difference between substances 2. warm to cold only 3. rate of transfer depends on temperature difference






47. At high temperatures a material stretches






48. 1. high pressure cutout 2. oil pressure cutout 3. pressure relief devices






49. Cannot go below -18






50. Condensing turbines exhaust steam at...
