← TechnologyWhich outcome occurs when a marine propeller experiences extensive cavitation near the blade tips?
A)Reduced thrust and increased vibration✓
B)Increased efficiency and lower noise
C)Improved fuel economy and smoother ride
D)Decreased drag and higher top speed
💡 Explanation
When cavitation occurs on a propeller, vapor bubbles form and collapse violently because rapid pressure changes reduce local pressure below the liquid's vapor pressure, which reduces thrust and generates noise and vibration. Therefore reduced thrust and vibration results, rather than increased efficiency/speed, which require stable hydrodynamic conditions.
