1. A barge is floating in freshwater. It has length 143m, beam 58m, and draft 5.35m. Find its displacement in freshwater, and its new draft if it moves into water with RD = 1.012 t/m³?

2. A box-shaped vessel floating in salt water is 46-m long, 11m wide, and has a light draft of 0.77m. How many tonnes of cargo must be loaded to increase the draft to 4.4m?

3. The length of a vessel is 203 m, breadth 59 m, and the waterplane area is 7,394 m². What is the vessel's waterplane coefficient, C_w?

4. Find the block coefficient C_b of a ship with underwater volume of 23,650.75 m³, 145-m long, 34-m wide, a draft of 5.75 m?

5. Suppose a vessel is being loaded in a salt-water port, where the waterplane coefficient C_w is 0.65 the length of the vessel at the waterline L is 75 m, the beam of the vessel at the waterline B is 14 m Find the TPC?
