1. When applying to write a Power Engineer certificate of competency examination, the
candidate must:
A) Undergo mandatory drug testing
B) Hold the next lower class of qualification
C) Pass a criminal records check
D) Pass both a written and oral examination
Answer: B – To write a Power Engineer certificate exam, the candidate must hold the next lower
class of qualification (or meet equivalent educational requirements approved by the
Administrator).

2. A machine lifts a load of 12 kN with an applied effort of 4 kN. What distance will the load
move if the effort moves a distance of 8 m and the efficiency of the machine is 70%?
A) 0.54 m
B) 3.81 m
C) 1.87 m
D) 0.38 m
Answer: C – Efficiency = (Load × Load Distance) / (Effort × Effort Distance). 0.70 = (12 kN × d) / (4
kN × 8 m). Solving: d = (0.70 × 4 × 8) / 12 = 22. = 1.87 m.
3. Which of these is the "Mechanical Refrigeration Code"?
A) ASME MRC
B) CSA B51
C) CSA B52
D) ASME Section I
Answer: C – CSA B52 is the Mechanical Refrigeration Code. CSA B51 is the Boiler, Pressure
Vessel, and Pressure Piping Code. ASME Section I covers Power Boilers.

4. In order to ensure safe and continuous operation of a pressure reducing valve, the valve
station should have:
A) A safety valve on the high-pressure side
B) A bypass line, plus a safety valve and pressure gauge on the low-pressure side
C) Thermometers on the inlet and outlet piping
D) A strainer immediately downstream of the valve
Answer: B – A properly designed pressure reducing valve station requires a bypass line for
maintenance, plus a safety valve and pressure gauge on the low-pressure side to protect
downstream equipment.
5. If the power dissipated by a resistor is 1.2 kW when supplied with 110 V, the amperage will
be:
A) 91.666 A
B) 19.006 A

C) 10.91 A
D) 132 A
Answer: C – Using P = VI, I = P/V = 1200 W / 110 V = 10.91 A.
6. The inclined "U" tube manometer:
A) Will measure pressure in MPa
B) Can only be used with mercury
C) Is more accurate than the "U" tube manometer
D) Is more difficult to read than the U-tube manometer
Answer: C – The inclined "U" tube manometer provides greater sensitivity and accuracy than the
standard U-tube manometer due to the放大 effect of the inclined scale.
7. A valve which gives good throttling action, takes less actuator force, but does not seal well is
