6 sample questions

Question 1.
Define the conservation of mass in your own words.
Show hintHide hint
Think about how mass is neither created nor destroyed.
Question 2.
What is a fixed control volume?
Show hintHide hint
Consider a container that remains in the same place.
3Question 3.
True or False: Conservation of mass is only applicable to incompressible fluids.
- True
- False
Show hintHide hint
Consider if mass can ever change form in fluid dynamics.
4Question 4.
What is a key feature of moving control volumes?
- They do not change shape over time.
- They move with the fluid flow.
- They contain multiple fluids.
Show hintHide hint
What distinguishes a moving control volume from a fixed one?
Question 5.
Given a cylindrical tank with a consistent inflow and outflow rate, calculate the time it takes for the tank to fill up. Assume the input and output rates are equal.
Show hintHide hint
Focus on the conservation principle; if inputs equal outputs, the volume remains unchanged.
Question 6.
Analyze a scenario where a ship moves through a river. How does the relative velocity between the ship and water affect the mass flow rate?
Show hintHide hint
Estimate the fluid velocity concerning the ship's movement.
