Question 1.
What is the conservation of mass?
Show hintHide hint
Think about a balloon - if you inflate it, the mass is the same before and after.
Question 2.
Give an example of an intensive property.
Show hintHide hint
These properties don’t change if you cut a piece out.
3Question 3.
What does conservation of energy imply in a closed system?
- Energy can be created
- Energy can be destroyed
- Energy can be transformed
Show hintHide hint
Consider how a battery converts chemical to electrical energy.
4Question 4.
Is mass conserved in fluid systems?
- True
- False
Show hintHide hint
Think about whether you lose mass when moving it around.
Question 5.
A tank has inflow and outflow rates of 10 L/min and 8 L/min respectively. Calculate the change in water level in the tank over 5 minutes assuming no leaks.
Show hintHide hint
Consider net inflow over the time period.
Question 6.
Using the Reynolds transport theorem, explain how you would assess fluid flow in a hatchery system with varying inflow/outflow rates.
Show hintHide hint
Think about how inflow and outflow directly impacts conservation laws.
