9. Examples of Bernoulli's equation applications

Try these first

1. 1.

   What does Bernoulli's equation express?

   Hint

   Think about energy transformations in fluids.

2. 2.

   Name one application of Bernoulli's equation.

   Hint

   Consider where you have seen pressure used.

3. 3.

   What concept does Bernoulli's equation primarily illustrate?

   • Conservation of momentum
   • Conservation of energy
   • Conservation of mass

   Hint

   Think about the types of energy involved.

4. 4.

   True or False: The hydraulic grade line includes kinetic energy.

   • True
   • False

   Hint

   Remember what HGL represents.

5. 5.

   A water tank has a height of 10m. Calculate the exit velocity of water flowing out of a hole at the bottom.

   Hint

   Consider the energy transformation as the water exits.

6. 6.

   How would you calculate the pressure differences at two points in a venturi meter? If p1 = 100 kPa, p2 = 80 kPa, and A1 = 0.1m², A2 = 0.05m², find flow rate.

   Hint

   Remember to use continuity and Bernoulli's principles.
