Question 1.
What does Bernoulli's equation represent in fluid dynamics?
Show hintHide hint
Consider the types of energy involved.
Question 2.
What is head loss?
Show hintHide hint
Think about energy transformations in fluids.
3Question 3.
What is the main principle of Bernoulli's equation?
- Energy conservation
- Momentum conservation
- Mass conservation
Show hintHide hint
Think about what happens to energy in fluid flow.
4Question 4.
True or False: Head loss is only relevant in turbulent flow.
- True
- False
Show hintHide hint
Consider how friction plays a role in different flow types.
Question 5.
A fluid flows through a horizontal pipe with varying diameters. How would you use Bernoulli’s equation to find the velocity at narrower sections?
Show hintHide hint
Remember to consider the cross-sectional areas.
Question 6.
In an irrigation system, water flows at a measured velocity and pressure. If the pipe constricts, how does Bernoulli’s principle predict changes in pressure and speed?
Show hintHide hint
Use the continuity principle alongside Bernoulli’s equation.
