Discussion on common piping errors 011: Which of the following designs (the diagram shows the piping design for the pump inlet) is correct? A. B. Answer: B. To prevent cavitation, the pump inlet valve must be larger than or equal to the diameter of the pump inlet pipe; it cannot be smaller. PS: Excerpted from the Chemical Pipeline Design Manual
To prevent pump cavitation, the diameter of the pump’s inlet pipe must be greater than or equal to the pump’s inlet diameter. Therefore, B is correct.
