1.) Conduct an over speed trip on a turbine.
2.) How do you calculate water rate?
3.) You have 52 barrels of fuel oil with a specific gravity of .85. What does the fuel weigh? (1 gallon of water weighs 8.33 lbs).
4.) What does ANSI 31.1 say about blow off valves and piping on a boiler with an M.A.W.P. of 125 PSI?
5.) What is the factor of safety of a boiler with an M.A.W.P. of 275 PSI that has a safety valve set at 150 PSI? The old factor of safety was 4.
6.) When a process goes through volume and pressure variations but no temperature changes is called?
7.) Describe the construction and operation of a Kingsbury Thrust Bearing.
8.) Which turbine has more end thrust Impulse or Reaction and why?
9.) What is “Water Hammer” and how do you prevent it and remedy it?
10.) A direct stay 1” in diameter is attached to a flat surface of an HRT boiler. Would the diameter of a diagonal stay be supporting the same area? The diagonal stay is 60” in length and the length of the line drawn at a right angle to the surface supported is 48” (Answer is PFT – 32 ASME Code Section one)
