2.3.6. Fluid Dynamics in Ships

Try these first

1. 1.

   Define buoyancy and give an example.

   Hint

   Think about how objects behave when placed in water.

2. 2.

   What is Pascal's Law in simple terms?

   Hint

   Consider how pressure behaves in a sealed container.

3. 3.

   What principle states that pressure applied to a confined fluid is transmitted undiminished in all directions?

   • Bernoulli's Principle
   • Pascal's Law
   • Archimedes' Principle

   Hint

   Think about how pressure behaves in a closed pipe.

4. 4.

   True or False: Buoyancy is the force that allows ships to float.

   • True
   • False

   Hint

   Consider how the weight of the water displaced compares to the weight of the ship.

5. 5.

   A cylindrical tank with a 2-meter diameter is filled with water. If the tank is rotated, resulting in a surface height of 0.5 meters, calculate the acceleration of the water at the edge of the tank.

   Hint

   Use your understanding of the relationship between height and angular velocity in forced vortices.

6. 6.

   Design a ship hull that maximizes buoyancy while minimizing drag in a specific fluid condition. Discuss the implications of your design choices.

   Hint

   Think about real-world ships and how their designs relate to performance.
