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.

23. Overall master plan - comprehensive program






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






25. Large turbines couple together on a single shaft applied to one generator






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

32. 1. inlet to the convection section 2. betwen convection and radiant section 3. at radiant section outlet






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






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






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






36. Made of steel - used for double acting pistons - acts as a piston rod






37. Throttle body

40. Counter act force and load on thrust bearings






41. 1. evaporator coil






42. Increased efficiency due to decreased frictional losses






43. Results in pressure drop and increased velocity






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






45. On the exhaust side - drives the blower - being connected to the same shaft - increases power by 50-70% as more air is forced into the engine






46. Radiator type






47. Small pressure drop






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






49. Requires annual review of SOPs






50. Polymers (polyelectrolytes)
