14.3.3. Simplification in Steady Incompressible Flow

Try these first

1. 1.

   Define conservation of mass in fluid dynamics.

   Hint

   Think about what happens when fluid enters and exits a container.

2. 2.

   What is the difference between extensive and intensive properties?

   Hint

   Consider examples like mass versus temperature.

3. 3.

   Which of the following is a principle of conservation in fluid dynamics?

   • Conservation of Mass
   • Conservation of Pressure
   • Conservation of Temperature

   Hint

   Remember the balance of mass entering and leaving a system.

4. 4.

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

   • True
   • False

   Hint

   Recall examples like density or temperature.

5. 5.

   A pipe has steady incompressible flow with a known diameter. Water enters at a velocity v1 and exits at a different pressure. Explain how you would determine the exit velocity.

   Hint

   Think about the relationship between area and velocity in steady flow.

6. 6.

   In a system where the density of fluid significantly changes, how would that affect calculations if you initially assumed incompressible flow?

   Hint

   Consider how density fluctuations could affect mass and energy calculations.
