22.5.1. Assumptions and Conditions

Try these first

1. 1.

   What is one key assumption of Bernoulli's equation?

   Hint

   Think about how flow characteristics change over time.

2. 2.

   Define incompressible flow.

   Hint

   Consider what happens to a fluid under pressure.

3. 3.

   Which of the following is NOT an assumption of Bernoulli's equation?

   • Steady flow
   • Incompressible fluid
   • Friction present

   Hint

   Recall the conditions needed for Bernoulli's equation to apply.

4. 4.

   True or False: Bernoulli's equation can be used for compressible flows.

   • True
   • False

   Hint

   Think about the implications of compressibility in fluids.

5. 5.

   Calculate the pressure difference between two points in a horizontal flow where the velocity increases from 3 m/s to 6 m/s, given the properties of incompressible fluid.

   Hint

   Use the differences in velocity squared while considering the density of the fluid.

6. 6.

   Discuss the impact of neglecting the frictional forces on real-world applications of Bernoulli's principle.

   Hint

   Explore examples where energy conservation fails due to friction.
