  1. Question 1

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

  2. Question 2

    Code: QYOS What is the correct method to be used to obtain a reduced output from a centrifugal pump?
    • By throttling of the pump discharge valve.
    • By opening the pump recirculation line.
    • By throttling of the pump suction valve.
    • By adjusting the pump relief valve.

  3. Question 3

    Code: EGOG What information is required to evaluate the condition of a heat exchanger during operation?
    • Inlet and outlet temperatures and pressure drops across the heat exchanger for both fluids.
    • Inlet and outlet temperatures for the fluid being cooled.
    • Pressure drop for both fluids.
    • Inlet and outlet temperatures of the cooling water.

  4. Question 4

    Code: PLDX Why is it necessary to carry out routine tests of the water in a diesel engine cooling water system?
    • To check that the correct concentration of corrosion inhibitors are maintained.
    • To check for the presence of contaminants in the system.
    • To check that the O-ring seals are in good condition.
    • To check for leakage in the cooling water system.

  5. Question 5

    Code: AOHG How often should water testing of a diesel engine cooling water system be carried out to check treatment levels and water condition during normal engine operation?
    • Once a week.
    • Once a day.
    • Once a month.
    • It doesn't matter as water condition for diesel engine cooling systems is not important.
