Q

A vessel loads edible oil in a deep tank through a manhole at the mid-length of the tank. In order to fill the tank to maximum capacity, what trim should the vessel have?

🔍 Key Concepts

• Effect of trim (bow up/bow down) on the liquid level along the length of a tank • Location of the manhole at mid-length versus the ends of the tank • How a free surface in a deep tank finds its own level (horizontal plane)

💭 Think About

• Sketch a side view of the ship, the deep tank, and the manhole at mid-length. If the liquid surface is always level, what happens at the ends of the tank when the ship trims by bow or stern? • Which trim condition would allow you to keep filling through a mid-length opening until the liquid just reaches the highest end of the tank? • Compare how much volume is available in the tank when the ship is level versus trimmed: in which case can you "push" the liquid highest at the ends?

✅ Before You Answer

• Make sure you visualize the liquid surface as a flat, horizontal plane inside a tank that is tilted by trim • Confirm where the highest point inside the tank is when the ship is trimmed by the bow, by the stern, or level • Verify which trim condition lets the tank be completely full at both ends while still filling through a mid-length manhole
