24.6.3. Total Energy along Streamlines

Try these first

1. 1.

   What is Bernoulli's equation used for?

   Hint

   Think about energy types in fluids.

2. 2.

   Name the three types of energy in Bernoulli's equation.

   Hint

   Remember PKE from our discussion.

3. 3.

   Which component is NOT part of Bernoulli's equation?

   • Pressure Energy
   • Kinetic Energy
   • Negative Energy

   Hint

   Recall the energy components we discussed.

4. 4.

   True or False: The energy gradient line can be flat if there is no flow.

   • True
   • False

   Hint

   Think about energy differences in systems.

5. 5.

   A water pipe has an entrance with a diameter of 0.3m and a velocity of 4m/s. It narrows to 0.1m. Calculate the exit velocity.

   Hint

   Use the continuity principle for fluids.

6. 6.

   In a fluid system, the energy gradient line was measured at several points, showing a decrease from 15m to 10m over a distance of 100m. What does this imply about energy loss?

   Hint

   Consider how energy is converted to other forms in a flowing fluid.
