3.2. Control Volume Considerations

Try these first

1. 1.

   What is a control volume?

   Hint

   Think about the boundaries where measurements are taken.

2. 2.

   What type of properties does Reynolds transport theorem relate?

   Hint

   Consider properties that change with the volume of fluid.

3. 3.

   What does a control volume help analyze?

   • Temperature changes
   • Fluid flows
   • Chemical reactions

   Hint

   Remember, it's about fluid behavior.

4. 4.

   True or False: Extensive properties do not depend on the amount of fluid present.

   • True
   • False

   Hint

   Consider what happens as the volume changes.

5. 5.

   A cylindrical tank has two inlets and one outlet. If water enters each inlet at different velocities and densities, how would you compute the overall flow rate leaving the outlet? Consider the effects of pressure and velocity variations across the tank.

   Hint

   Focus on the contributions from both inlets and the outlet area.

6. 6.

   Design a control volume model for a turbine and identify key inputs and outputs. Explain how the Reynolds transport theorem applies to it.

   Hint

   Consider energy conservation principles and flow characteristics.
