Power Engineering 3

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. There is no relative movement between the rotor bars and teh flux of the rotating field - countacts speed changes






2. Need as many brushes as poles






3. Compressed gas






4. Flammables and combustibles






5. Is the free electrons that are attracted by the positive terminal of thevoltage supply and will flow out continuously from the negative terminal






6. Pulse generator operates at 3-40kHz






7. Useful amount of flux per pole






8. I - NPS 63mm II - NPS 38mm III - NPS of bother 63mm and 38mm






9. Storage facility not required - Clean burning - no ash - Stack emission are relatively clean - Easily mixed with air - Does not require any extensive handling equipment - Easy to control






10. Refer to pg 27.2.1 of ASME academic extract - do not interpolate between values - select next higher rated value






11. Oxidizing materials






12. Shunt - series and compound wound






13. Current carrying conductor placed in a magnetic field and the conductor distorts the magnetic fields between the poles - fleming's left hand rule






14. Liquid being measured must be able to mix with the gas or air in the bubbler






15. 1. natural gas 5-10% 2. oil 5-15% 3. coal (pulverized) 15-30% 4. coal (stoker fired) 25-50%






16. Ring type joint gaskets






17. Due to upsets in the secondary variable - first controller called the 'slave' or inner loop and the second controller is called the 'master' or outer loop






18. 1. carbon 2. hydrogen 3. sulphur






19. Wander erratically






20. Conencted to transformers or inside switchgears






21. No communicators - voltage can be transformed up or down and has slip rings






22. Oscillate - on - off control behavior






23. Motor control center






24. Just enough oxygen for complete combustion






25. Pancake or concentric






26. Smallest cross sectional area






27. Impact force - +- 0.5% accuracy - good in corrosive environments - up to 10000kPa and 400 degrees






28. The nature of atoms and the manner in which they behave when subjected to variuos forces and conditions






29. Design number followed by the provinces - the registered - the design in chronological order proceeding the decimal






30. The sum of individual current through each loop or path are equal to the total current






31. Where shock loading may occur






32. % moisture - fixed carbon






33. Heavy load deman






34. 1. product identifier 2. information for safe handling 3. hazardous symbol - first aid - safe handling 4. reference to MSDS






35. Adjustable speed






36. Thermocouple connected in series






37. Combination of shunt and series






38. To provide electrical power for whatever need in a safe and dependable manner






39. Stationary conductors






40. Poisonous and infectious materials






41. One controlled variable and two manipulated variable as output - 'Duplex Controlres






42. Cannot be over 75m away from building - average of 12.2m away from building






43. Dark brown in color - laminar structure - often with remnants of woody fibers present. Tough but not hard - when exposed to air it loses moisture rapidly and crumbles






44. Is the total opposition - Z






45. Second element of WHMIS






46. Used for combustion calculations






47. Magnetic flux produced by one coil that cuts the lines of the conductors of the second coil - creating a voltage induced in the second coil






48. 5 min delay






49. Free valence electrons are attracted by the positive terminal of the voltage supply and will flow out continuously from negative terminal into the circuit






50. Safety of the life and property
