    Explanation
    The working principle of a level transmitter in a high-pressure pump (HPP) is guided radar. Guided radar level transmitters use a probe that emits high-frequency electromagnetic waves. These waves travel down the probe and when they reach the liquid surface, they are reflected back to the transmitter. By measuring the time it takes for the waves to return, the transmitter can determine the level of the liquid in the HPP. Guided radar is commonly used in applications where there are harsh conditions, such as high pressures, and it provides accurate and reliable level measurements.

    With Increase in Operating Speed, Centrifugal Pumps NPSH requirement…

    • A.

      Increases

    • B.

       Decreases

    • C.

       Remains Unaltered

    • D.

      Can either increase or decrease depending on other parameters

    Correct Answer
    A. Increases
    Explanation
    As the operating speed of centrifugal pumps increases, the NPSH (Net Positive Suction Head) requirement also increases. NPSH is the amount of pressure required at the pump's suction side to prevent cavitation, which can cause damage to the pump. When the operating speed increases, the pressure at the suction side decreases, leading to a higher NPSH requirement to maintain stable operation. Therefore, the correct answer is that the NPSH requirement increases with an increase in operating speed.
