15. Fluid Mechanics

Try these first

1. 1.

   What is the term for the ratio between inertial forces and viscous forces in fluid dynamics?

   Hint

   Think about how flow types are determined.

2. 2.

   Name the three types of similarities in fluid dynamics.

   Hint

   They represent different aspects of models versus prototypes.

3. 3.

   What does Bernoulli's theorem describe?

   • Conservation of mass
   • Conservation of energy
   • Conservation of momentum

   Hint

   Consider which fundamental principle this validates.

4. 4.

   True or False: Dynamic similarity can exist without geometric similarity.

   • True
   • False

   Hint

   Think about prerequisite conditions.

5. 5.

   Devise an experiment to test the flow around a scaled-down dam model and describe the parameters you would measure.

   Hint

   Consider how you might display data for comparisons.

6. 6.

   Explain how to compute the Froude number for a model wave in a flume and how it relates to the prototype ocean waves.

   Hint

   Recall the relationship between length and velocity.
