23.5.1. Summary of Key Principles

Try these first

1. 1.

   Define Bernoulli's Equation.

   Hint

   Think about the conservation of energy in fluid flow.

2. 2.

   What is meant by incompressible flow?

   Hint

   Consider liquids like water.

3. 3.

   Bernoulli's equation applies to which kind of flow?

   • Steady Flow
   • Unsteady Flow
   • Turbulent Flow

   Hint

   Think about the definition of steady and unsteady flows.

4. 4.

   True or False: Bernoulli's equation can be applied to compressible fluid flows.

   • True
   • False

   Hint

   Consider what incompressible means in terms of density.

5. 5.

   A tank filled with water has a hole at the bottom. Derive the exit speed of water using Bernoulli's equation if the water surface is at height h.

   Hint

   Recall the relationship between potential energy and kinetic energy.

6. 6.

   Explain how energy loss due to viscosity would affect an application using Bernoulli's equation, suggesting ways to account for these losses.

   Hint

   Think about how energy conservation might be altered in viscous flows.
