← TechnologyWhich outcome occurs when a hydraulic pump operates with an insufficiently filled reservoir?
A)Cavitation erosion of impeller surfaces✓
B)Increased fluid bulk modulus operation
C)Improved thermal transfer efficiency rate
D)Stable laminar fluid flow conditions
💡 Explanation
Insufficient fluid causes vapor bubbles to form and collapse violently during **cavitation**, eroding the pump's impeller. This occurs because reduced inlet pressure vaporizes the fluid, therefore cavitation occurs, rather than efficient pumping.
