Which of the following is a primary reason for a pump operator to bleed air from the system?

Bleeding air from the system is crucial because it helps to avoid cavitation, which is a condition that can cause significant damage to the pump and reduce its efficiency. Cavitation occurs when there are pockets of vapor that form in a liquid, leading to the formation of bubbles. These bubbles can collapse violently, creating shock waves that can erode the pump impeller and result in mechanical failure.

By bleeding air out of the system, the pump operator ensures that the pump operates with a consistent and unimpeded flow of liquid. This procedure helps to maintain the proper pressure within the pump and prevents the conditions that lead to cavitation. Overall, ensuring that the system is free of air not only enhances the pump's performance but also prolongs its operational life by protecting its components from the harmful effects associated with cavitation.
