Show hintHide hint
Think about mass conservation in a fluid system.
Question 2.
List the three laws of conservation discussed in class.
Show hintHide hint
Recall the laws that govern physical systems.
3Question 3.
What is the continuity equation?
- It relates pressure to flow.
- It expresses mass conservation.
- It calculates energy loss.
Show hintHide hint
Think about how fluids behave in closed systems.
4Question 4.
True or False: The conservation of momentum is analogous to Newton's first law.
- True
- False
Show hintHide hint
Recall the relationship between force and change in motion.
Question 5.
Consider a fluid flowing through a pipe that narrows at one point. If the velocity at the wider section is 2 m/s and the diameter changes, how does this affect pressure according to the Bernoulli principle?
Show hintHide hint
Think about how flow speeds up in smaller areas.
Question 6.
A tank has an inflow of 5 L/minute and an outflow of 4 L/minute. What is the change in the mass of fluid in the tank over 10 minutes?
