Which outcome occurs when an unprimed centrifugal pump attempts to move water?

💡 Explanation

When an unprimed centrifugal pump attempts to move water, an airlock occurs because air occupies the impeller and inlet, impeding the ability for it to generate suction, thus preventing the liquid from entering. Therefore, an airlock will occur, rather than damage, overheating, or electrical insulation failure, which require the pump moving fluid under increased stress.
