Question 2.
How do you define irrotational flow?
Show hintHide hint
Consider the definition of rotation in fluids.
3Question 3.
What does the equation of continuity express?
- Mass conservation

Show hintHide hint
Think about what it means for substances flowing through a system.
4Question 4.
Irrotational flow is defined by which condition?
- True
- False
Show hintHide hint
Look at the properties of fluid rotation.
Question 5.
You have a fluid flowing through a pipe that narrows from a diameter of 0.5 m to 0.25 m. Calculate the velocity if the inlet flow rate is 10 m³/s.
Show hintHide hint
Remember to convert diameters to radius for area calculations.
Question 6.
Given a velocity distribution of u = x² - y² in a flow field, determine if the flow is rotational or irrotational by evaluating the angular velocities.
Show hintHide hint
