Q

The free surface corrections depend upon the dimensions of the surface of the free liquids and the __________.

🔍 Key Concepts

• Free surface effect and how it impacts a vessel's stability • The difference between tank dimensions at the liquid surface and overall tank volume • How free surface correction is related to moment of inertia of the free surface rather than how full the tank is

💭 Think About

• Ask yourself: what part of the liquid in the tank actually moves and creates a heeling moment when the vessel inclines? • Consider whether free surface correction changes if a tank is half full versus almost full, assuming the same exposed surface area. • Think about which property of the vessel or tank determines how large the free surface moment becomes, aside from the size of the free surface itself.

✅ Before You Answer

• Verify which option relates to a property that directly affects stability calculations, not just the vessel’s geometry or tank location. • Check which factor, when increased, would always make free surface effect worse, even if the surface area stayed the same. • Eliminate any choices that deal with where the tank is, rather than with the physical effect of the liquid’s free surface itself.
