  1. Question 1

    Code: GITV What is the main reason for routine testing of the cooling water in a diesel engine cooling system?
    • To measure the pH-value of the water.
    • To detect dissolved oxygen in the water.
    • To ensure that the correct levels of chemical treatment are maintained at all times.
    • To detect the presence of contaminants in the water.

  2. Question 2

    Code: JOKT What action should be taken if the heat transfer capacity of a heat exchanger operating as a lubricating oil cooler is reducing?
    • Increase the cooling water pressure.
    • Decrease the lubricating oil flowrate.
    • Increase the lubricating oil flowrate.
    • The heat transfer surfaces should be cleaned.

  3. Question 3

    Code: BNKJ Choose the option which is most likely to result in erosion of the tubes in a heat exchange:
    • Cooling water temperature too high.
    • Cooling water pressure too high.
    • Cooling water velocity too high.
    • Rate of heat transfer too high.

  4. Question 4

    Code: KVRG What is the recommended range for the pH-value for the water in a diesel engine cooling system engine cooling water be maintained?
    • Below 5.
    • Between 5 and 7.
    • Between 7 and 10.
    • Above 10.

  5. Question 5

    Code: FCFD Consider a 450 volt, 859 kW rated generator has not been in operation for several weeks. Prior to starting, insulation resistance readings are taken. The minimum acceptable insulation resistance reading on the main stator winding to allow you to proceed with running the generator is:
    • 1 000 000 Ohms.
    • 10 Ohms.
    • 1 000 Ohms.
    • 10 000 Ohms.
