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.

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






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






23. Condensing turbines exhaust steam at...






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






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






26. The volum swept out by the piston - same through all stages






27. 1. plate 2. channel






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






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






30. Waste heat only






31. 1. throttle inlet valve 2. reduce compressor speed 3. automatic discharge vent line 4. anit- surge valve - reciruclation 5. anti- surge microprocessor - kickback valve






32. Countries with small grids or specail grid requirements - has a high efficiency at base loads






33. Centrifugal pumps






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






35. Use teflon or carbon to lubricate system






36. Straight condensing






37. Air flow is upward

42. Compression ignititon engines






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






44. A concentrated solution at its critical point






45. King valve






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






47. Made of cast iron and support by stay bolts to protect against a vacuum
