🔍 Key Concepts

• Shape and purpose of a fairwater cone on a propeller • How flow behaves around the hub and shaft of a propeller • Typical methods used to reduce electrolytic (galvanic) corrosion on ships

💭 Think About

• Think about what happens to water flow if there is a blunt propeller hub versus a smoothly faired cone behind it. • Ask yourself which of the listed functions normally require special materials or electrical arrangements, not just a change in shape. • Consider whether a fairwater cone is mainly a hydrodynamic device, a mechanical device, or an electrical protection device.

✅ Before You Answer

• Identify which option(s) relate directly to streamlining and smooth water flow around the propeller hub. • Check which function typically uses sacrificial anodes or impressed current systems, and whether a fairwater cone fits that role. • Decide if a single, simple steel cone is realistically designed to perform all three of the listed functions, or if one (or two) are the primary purpose(s).
