5.3.3. Bernoulli’s Equation Assumptions

Try these first

1. 1.

   What does steady flow imply in fluid mechanics?

   Hint

   Think about consistency over time.

2. 2.

   Why is incompressible flow an important assumption for Bernoulli's equation?

   Hint

   Consider how liquids behave compared to gases.

3. 3.

   What condition must be true for Bernoulli's equation to apply?

   • Viscous Flow
   • Steady Flow
   • Irregular Flow

   Hint

   Consider time consistency in fluid properties.

4. 4.

   True or False: Bernoulli’s equation applies to compressible fluids.

   • True
   • False

   Hint

   Recall the assumptions about density.

5. 5.

   A horizontal pipe has varying diameters; explain how you would analyze the flow using Bernoulli's equation, considering viscosity.

   Hint

   Remember to connect flow rate changes with velocity gradients in different pipe sections.

6. 6.

   In a real-world scenario where water flows through a system with significant friction, develop a strategy using Bernoulli's equation to estimate the pressure drop.

   Hint

   Think about how you could calculate losses in different sections of a pipe system.
