5. Fluid Mechanics

Try these first

1. 1.

   Define Bernoulli's equation.

   Hint

   Recall the terms included in the equation: pressure, kinetic energy, and potential energy.

2. 2.

   What is a control volume?

   Hint

   Think about the space through which fluid flows.

3. 3.

   What does Bernoulli's equation relate?

   • Pressure and Temperature
   • Pressure
   • Kinetic Energy
   • and Potential Energy
   • Flow Rate and Depth

   Hint

   Remember the energy forms included in the equation.

4. 4.

   True or False: Steady flow means fluid properties change over time.

   • True
   • False

   Hint

   Consider the definition of steady flow.

5. 5.

   Calculate the pressure difference between two points in a tube where water flows at 4 m/s in a wider section and 10 m/s in a narrower section.

   Hint

   Set the equations for both points and solve for pressure.

6. 6.

   Design an experiment to demonstrate Bernoulli's principle using household items.

   Hint

   Think creatively about air pressure and fluid dynamics.
