🔍 Key Concepts

• How changes in pressure around a propeller blade affect the surrounding water • The difference between loss of thrust due to water flow and physical damage to the blade surface • Key symptoms: voids/bubbles, pitting, and vibration near the propeller

💭 Think About

• Which option refers to the formation and collapse of vapor bubbles or voids in a liquid around the propeller blades? • Which terms in the choices are normally used to describe distance-related performance of a propeller rather than physical damage? • Think about which phenomenon is most commonly associated with erosion or pitting on the leading and trailing edges of propeller blades.

✅ Before You Answer

• Identify which term is directly linked to bubbles/voids forming on the blades due to low pressure. • Eliminate any choices that mainly describe how far a ship moves per propeller revolution instead of blade damage. • Confirm which term is typically associated with noise, vibration, and pitting on the propeller.
