3.2. Conservation of Energy and Bernoulli's Equation

Try these first

1. 1.

   Define Bernoulli's equation.

   Hint

   Look for the terms energy conservation.

2. 2.

   What is specific energy?

   Hint

   Think about energy related to depth and velocity.

3. 3.

   What does Bernoulli's equation relate?

   • Pressure
   • Velocity
   • Elevation
   • Temperature
   • Pressure
   • Only Pressure

   Hint

   Think about energy types in fluid mechanics.

4. 4.

   True or False: Specific energy is a measure of the total energy available in the flow.

   • True
   • False

   Hint

   Consider energy distribution in fluids.

5. 5.

   Given a flow of water at a rate of 10 cubic feet per second over a ramp with a height of 2 feet, calculate the surface elevation downstream.

   Hint

   Consider energy conservation and any losses due to friction.

6. 6.

   A channel transitions from subcritical to supercritical flow. What structures would you design to mitigate flow changes?

   Hint

   Think about how different structures influence flow speeds.
