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. The chemical union of the combustible elements of a fuel and the oxygen in the air - at a rate that produces useful heat energy






2. Must be registered with the Provincial Boilers and Safety Division in local area






3. Is the total opposition in a curcuit to the flow of the current






4. Second element of WHMIS






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






6. 1. wet pipe 2. dry pipe 3. preaction - double interlocked 4. combination of dry and preaction 5. deluge






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






8. Salient and cylindrical






9. Current after voltage - inductive load






10. Is the total opposition - Z






11. The ratio of change of output to change of input






12. Sum of current flowing away = sum flowing towards - and any closed path in an electrical circuit the sum of the voltages is zero as current passes through the resistors


13. 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






14. Exactly the theoretically amount of air necessary was supplied and the combustibles were all completely burned






15. Produces sticky - cohesive mass when heated - carbon content is lower than anthracite - but volatile matter content is higher.






16. % moisture - fixed carbon






17. Lowers wasted heat - lowers power requriements for forced draft and induced draft fans






18. Used to linearize the measurement signal






19. Used in building over 3 stores - 14m






20. The percent of the process variable range that causes 100% change in the controller output






21. Opposition to liquid head pressure






22. Corrosive materials






23. Promote safety and uniformity in the design - construction - installation - operation - testing - and repair of boilers - pressure vessels - and related equipment






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






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






26. Break contact with the line side first - line side first when installing






27. 1. product identifier 2.hazard symbol 3. risk phases 4. precautionary statement 5. fist aid 6. supplier information 7. reference to MSDS






28. Canadian Standard Association (CSA) - American Society of Mechanical Engineers (ASME) - National Board of Boiler and Pressure Vessel Inspectors (NBBI)






29. Just enough oxygen for complete combustion






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






31. High heat transfer coefficient - low density (1/4 of air) and can increase output up to 20-30% of transformer






32. Oscillate - on - off control behavior






33. More expensive - Involves the use of long large diameter pipelines - Hydrogen content in gas decreases the efficiency of combustion. Each kg of hydrogen produces 9 kg of water






34. 1. identify probable emergencies 2. notification process (who and when) 3. determine immediate personal actions to be taken 4. minimize adverse effects on personnel - property and environment






35. Mircroprocessors - memory - inputs/outputs - terminals - power supply






36. Gas only applications - lobe impellars






37. RTD's in slots of stator windings






38. Casues the neutral plane within whcih brushes have been placed to shift - so that the brushes are now shorting the coils - which produce voltage (sparking) - use interpoles to neutralize condition






39. Establish rules of safety covering the design - fabrication - and inspection during construction of boilers and pressure vessels - and to interpret these rules when questions arise






40. 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






41. Defined as that quantity of a substance that has a mass in kilograms equal to its molecular mass






42. CO2 - SO2 - H20 - N2 and ash






43. Speed conditions - strength of field - number of conductors






44. Poisonous and infectious materials






45. Load current is also the excitation current - never operate without a load - has high starting torque






46. Expensive - externally mounted - not accurate for densisty changes






47. Prevents/dampens external vibration






48. Thermally sensitive resistor - negative tempertaure co- efficient - non linear with temperature






49. Is the instantaneous values through one cycle(squared) the average






50. Current is changing value. AC continuous changes generates alternating emf unit H - herny - symbol is 'L'
