- What is the definition of the velocity potential?
- Is the velocity potential a scalar or a vector?
- Units of the velocity potential?
- What is definition of the stream function? Is it a scalar or a vector? Units of the stream function? For an ideal fluid with irrotational flow motion:
- Write the condition of irrotationality as a function of the velocity potential.
- Does the velocity potential exist for (a) an irrotational flow and (b) for a real fluid?
- Write the continuity equation as a function of the velocity potential. Further, answer the following questions:
- What is a stagnation point?
- For a two-dimensional flow, write the stream function conditions.
- How are the streamlines at the stagnation point?
