Show hintHide hint
What does it allow us to analyze?
Question 2.
What does the continuity equation represent?
Show hintHide hint
Think about conservation.
3Question 3.
What is a control volume used for?
- To calculate temperature of fluid
- To analyze fluid flow properties
- To measure fluid viscosity
Show hintHide hint
Remember its purpose in fluid analysis.
4Question 4.
True or False: The Reynolds transport theorem connects system changes to control surface flow.
- True
- False
Show hintHide hint
Think about how properties change in time and space.
Question 5.
A cylindrical tank has a diameter of 3m and a height of 5m. Water is flowing out at a rate of 10 liters per second. Calculate how fast the water level is dropping.
Show hintHide hint
Relate the flow out to the height change.
Question 6.
A water jet strikes a flat surface at a velocity of 15 m/s. If the jet has a diameter of 0.1m, calculate the force exerted on the surface.
Show hintHide hint
Consider momentum change because the water comes to rest on impact.
