6 sample questions

Question 1.
What does the conservation of mass imply in fluid dynamics?
Show hintHide hint
Think about how mass behaves in a closed system.
Question 2.
What is the continuity equation in simplified form for incompressible flow?
Show hintHide hint
Consider the implications of constant density.
3Question 3.
What is the fundamental premise of the continuity equation?
- Flux increases with time
- Mass is conserved
- Pressure decreases in a system
Show hintHide hint
Think about definitions involving conservation.
4Question 4.
The continuity equation can be simplified under which condition?
- True
- False
Show hintHide hint
Explore what happens to density.
Question 5.
A pipeline has a diameter of 4 cm at point A and 2 cm at point B. If water flows with a speed of 2 m/s at point A, calculate the speed of water at point B using the continuity equation.
Show hintHide hint
Remember, Area = π*(diameter/2)^2 and mass flow conservation.
Question 6.
Explain how the continuity equation would apply to a spillway designed to manage river flow during flooding. What implications does it have for structural engineering?
Show hintHide hint
Consider how flow constriction might affect velocity and design.
