Question 1.
Define Control Volume in your own words.
Show hintHide hint
Think about what a volume represents in the physical context of fluid flow.
Question 2.
What does Reynolds Transport Theorem relate?
Show hintHide hint
Consider how we connect quantities over time to the boundaries of a volume.
3Question 3.
What does Reynolds Transport Theorem primarily help us with?
- Describing temperatures in fluids
- Linking system properties to control volumes
- Defining fluid viscosity
Show hintHide hint
Think about how properties affect control volumes.
4Question 4.
True or False: In steady flow, the time derivatives in Reynolds Transport Theorem can be neglected.
- True
- False
Show hintHide hint
Consider the implications of properties changing over time.
Question 5.
A large tank has an inflow of 100 lit/sec and an outflow of 80 lit/sec. Calculate how the mass storage changes in the tank over a 10-minute period.
Show hintHide hint
Consider the net inflow and multiply by time to find total change.
Question 6.
For a control volume with body force due to gravity and a lateral surface force due to pressure change, derive the equation for momentum change.
Show hintHide hint
Start from Newton’s second law and consider how each force contributes.
