    A. Move large amounts of liquids usually at low pressure.
    Explanation
    Centrifugal pumps are designed to move large amounts of liquids usually at low pressure. This means that they are capable of transferring a significant volume of liquid, but not at a high pressure. They are commonly used in applications such as water supply, irrigation, and wastewater treatment, where a large volume of liquid needs to be moved efficiently. They are not designed specifically for pumping only oil, and they are not intended for pumping liquids into high pressure.

    • 30 sec

    • 45 sec

    • 90 sec

    Correct Answer
    A. 45 sec
    Explanation
    The upper master valve, also known as the SSV (Surface Safety Valve), is the only safety valve on the wellhead tree that needs to close within 45 seconds of Emergency Shut Down (ESD) activation. This quick closure is crucial in preventing any potential hazards or uncontrolled release of fluids from the wellhead. By closing within 45 seconds, the SSV helps to maintain the integrity and safety of the wellhead system.

    Separators 8.        It is OK to put a lower rated needle valve on a vessel as long as the pressure coming in won’t exceed the needle valve’s rating. (EX: 1440 psi vessel with 1000 psi needle valve)

    • True

    • False

    Correct Answer
    A. False
    Explanation
    It is not okay to put a lower rated needle valve on a vessel, even if the pressure coming in won't exceed the needle valve's rating. This is because the needle valve may not be able to handle sudden pressure surges or fluctuations, which can lead to failure and potential safety hazards. It is important to always use a needle valve that is rated equal to or higher than the maximum pressure expected in the system.
