Why can air binding occur, and how can it be mitigated in a pumping system?

• A. Air in the suction line cools the fluid and improves flow; use larger pipe.
• B. Air in the discharge piping reduces efficiency and cavitates; mitigate with proper venting, priming, and sealed lines.
• C. Air in the discharge piping has no effect on efficiency.
• D. Air in the discharge piping reduces efficiency but cannot cavitate.

Answer: (B)
