3. Questions and Discussion

Try these first

1. 1.

   Define Bernoulli's equation in your own words.

   Hint

   Think about the different energy forms involved in fluid motion.

2. 2.

   What does the term 'specific energy' refer to?

   Hint

   Remember, it’s about the energy attributed to a mass of fluid.

3. 3.

   What is the primary effect of Bernoulli's equation on fluid flow?

   • It increases pressure
   • It conserves energy
   • It reduces flow rate

   Hint

   Think about what the equation represents in terms of fluid dynamics.

4. 4.

   Is specific energy related to the fluid depth in an open channel?

   • True
   • False

   Hint

   Remember the equation connecting depth and energy.

5. 5.

   Consider a rectangular channel with an upstream depth of 3 feet and a flow rate of 6.5 ft²/s. Calculate the downstream elevation if raised over a 1-foot ramp, discussing energy losses.

   Hint

   Focus on establishing a clear relationship between upstream and downstream depths.

6. 6.

   A river transitions from a steep cliff into a wooden ramp over 0.5 feet. Analyze the flow behavior during this transition and how adjustments to z1 affect the water's critical depth.

   Hint

   Consider both energy inputs and losses due to ramp height.
