Question 1.
Define 'system' in fluid mechanics.
Show hintHide hint
Think of it as the mass or fluid being analyzed.
Question 2.
What does a control volume refer to?
Show hintHide hint
Remember, it's more about the volume in space.
3Question 3.
What does a control volume represent in fluid mechanics?
- A fixed mass of fluid
- A defined space for analysis
- A dynamic fluid system
Show hintHide hint
Consider the volume aspect.
4Question 4.
True or False: The conservation of momentum states that momentum can be created.
- True
- False
Show hintHide hint
Think about conservation principles.
Question 5.
A cylindrical tank at rest is filled with water. Calculate the pressure at the bottom if the height of the water is 5 meters. Assume the density of water is 1000 kg/m^3.
Show hintHide hint
Use the hydrostatic pressure equation!
Question 6.
A jet of water striking a flat plate at 30 degrees creates a force. How can you calculate this using conservation principles?
Show hintHide hint
Consider the flow rate and angle of incidence!
