🔍 Key Concepts

• propeller pitch speed vs ship’s actual speed through the water • difference between apparent slip and true slip • how a fraction or percentage based on pitch speed is normally defined in propulsion theory

💭 Think About

• Think about what it means when the propeller should drive the ship a certain distance per revolution, but the ship actually moves a different distance. • Ask yourself: if you compare the difference between theoretical speed and actual speed to the theoretical speed itself, what are you really measuring? • Which term is commonly used for the percentage by which the propeller ‘falls short’ of its theoretical advance?

✅ Before You Answer

• Check which terms in the choices are specifically related to slip of the propeller. • Verify which type of slip is normally expressed as a ratio or percentage using pitch speed as the denominator. • Make sure you can distinguish between a simple geometric concept (pitch) and performance-related measures (slip and propulsive efficiency).
