2. Fluid Dynamics

Try these first

1. 1.

   Define fluid dynamics in your own words.

   Hint

   Think about how fluids act when they flow.

2. 2.

   What is an extensive property? Provide an example.

   Hint

   Consider properties that change if you had more or less fluid.

3. 3.

   What is fluid dynamics primarily concerned with?

   • Fluids at rest
   • Fluids in motion
   • Fluid properties only

   Hint

   Think about what happens when fluids flow.

4. 4.

   True or False: Intensive properties depend on the amount of the fluid present.

   • True
   • False

   Hint

   Consider how changing the volume of fluid affects properties.

5. 5.

   A tank filled with water is connected to a pipe with varying diameters. If water is flowing out at a constant rate, apply the Reynolds transport theorem to explain how the properties change as the water flows through the narrowing pipe.

   Hint

   Consider the principles of continuity and Bernoulli's equation.

6. 6.

   In a river entering a valley (control volume), describe how you would apply the Reynolds transport theorem to analyze the change in the water's mass and velocity as it flows through different sections of the valley.

   Hint

   Think about how water speeds up or slows down at different points in the valley.
