What is NOT an advantage of centrifugal pumps over reciprocating pumps?
AI Explanation
The correct answer is B) They require priming for stripping.
Centrifugal pumps have several advantages over reciprocating pumps, such as pumping more cargo in less time (option A), being smaller for equivalent pumping ability (option C), and being less expensive (option D). However, centrifugal pumps do require priming for stripping, which is a disadvantage compared to reciprocating pumps that do not require priming. Priming is the process of filling the pump casing with liquid to ensure proper operation, which is necessary for centrifugal pumps to function efficiently, especially when stripping the last of the cargo from a tank.
